Documentation/technical: include Scalar technical doc

Include 'Documentation/technical/scalar.txt' alongside the other HTML
technical docs when installing them.

Now that the document is intended as a widely-accessible reference, remove
the internal work-in-progress roadmap from the document. Those details
should no longer be needed to guide Scalar's development and, if they were
left, they could fall out-of-date and be misleading to readers.

-Roadmap
--------
-
-NOTE: this section will be removed once the remaining tasks outlined in this
-roadmap are complete.
-
-Scalar is a large enough project that it is being upstreamed incrementally,
-living in `contrib/` until it is feature-complete. So far, the following patch
-series have been accepted:
-
-- `scalar-the-beginning`: The initial patch series which sets up
-  `contrib/scalar/` and populates it with a minimal `scalar` command that
-  demonstrates the fundamental ideas.
-
-- `scalar-c-and-C`: The `scalar` command learns about two options that can be
-  specified before the command, `-c <key>=<value>` and `-C <directory>`.
-
-- `scalar-diagnose`: The `scalar` command is taught the `diagnose` subcommand.
-
-- `scalar-generalize-diagnose`: Move the functionality of `scalar diagnose`
-  into `git diagnose` and `git bugreport --diagnose`.
-
-- 'scalar-add-fsmonitor: Enable the built-in FSMonitor in Scalar
-  enlistments. At the end of this series, Scalar should be feature-complete
-  from the perspective of a user.
-
-Roughly speaking (and subject to change), the following series are needed to
-"finish" this initial version of Scalar:
-
-- Move Scalar to toplevel: Move Scalar out of `contrib/` and into the root of
-  `git`. This includes a variety of related updates, including:
-    - building & installing Scalar in the Git root-level 'make [install]'.
-    - builing & testing Scalar as part of CI.
-    - moving and expanding test coverage of Scalar (including perf tests).
-    - implementing 'scalar help'/'git help scalar' to display scalar
-      documentation.
-
-Finally, there are two additional patch series that exist in Microsoft's fork of
-Git, but there is no current plan to upstream them. There are some interesting
-ideas there, but the implementation is too specific to Azure Repos and/or VFS
-for Git to be of much help in general.
-
-These still exist mainly because the GVFS protocol is what Azure Repos has
-instead of partial clone, while Git is focused on improving partial clone:
-
-- `scalar-with-gvfs`: The primary purpose of this patch series is to support
-  existing Scalar users whose repositories are hosted in Azure Repos (which does
-  not support Git's partial clones, but supports its predecessor, the GVFS
-  protocol, which is used by Scalar to emulate the partial clone).
-
-  Since the GVFS protocol will never be supported by core Git, this patch series
-  will remain in Microsoft's fork of Git.
-
-- `run-scalar-functional-tests`: The Scalar project developed a quite
-  comprehensive set of integration tests (or, "Functional Tests"). They are the
-  sole remaining part of the original C#-based Scalar project, and this patch
-  adds a GitHub workflow that runs them all.
-
-  Since the tests partially depend on features that are only provided in the
-  `scalar-with-gvfs` patch series, this patch cannot be upstreamed.
