worktree: use 'worktree' over 'working tree'

Browse Source 
It is helpful to distinguish between a 'working tree' and a 'worktree'.
A worktree contains a working tree plus additional metadata. This
metadata includes per-worktree refs and worktree-specific config.

This is the first of multiple changes to git-worktree.txt, restricted to
the DESCRIPTION section.

@ -25,45 +25,49 @@ Manage multiple working trees attached to the same repository.
A git repository can support multiple working trees, allowing you to check
out more than one branch at a time. With `git worktree add` a new working
tree is associated with the repository. This new working tree is called a
"linked working tree" as opposed to the "main working tree" prepared by
linkgit:git-init[1] or linkgit:git-clone[1].
A repository has one main working tree (if it's not a
bare repository) and zero or more linked working trees. When you are done
with a linked working tree, remove it with `git worktree remove`.

In its simplest form, `git worktree add <path>` automatically creates a
new branch whose name is the final component of `<path>`, which is
convenient if you plan to work on a new topic. For instance, `git
worktree add ../hotfix` creates new branch `hotfix` and checks it out at
path `../hotfix`. To instead work on an existing branch in a new working
tree, use `git worktree add <path> <branch>`. On the other hand, if you
just plan to make some experimental changes or do testing without
disturbing existing development, it is often convenient to create a
'throwaway' working tree not associated with any branch. For instance,
`git worktree add -d <path>` creates a new working tree with a detached
`HEAD` at the same commit as the current branch.

If a working tree is deleted without using `git worktree remove`, then
its associated administrative files, which reside in the repository
(see "DETAILS" below), will eventually be removed automatically (see
`gc.worktreePruneExpire` in linkgit:git-config[1]), or you can run
`git worktree prune` in the main or any linked working tree to
clean up any stale administrative files.
`git worktree prune` in the main or any linked worktree to clean up any
stale administrative files.
If a linked working tree is stored on a portable device or network share
which is not always mounted, you can prevent its administrative files from
being pruned by issuing the `git worktree lock` command, optionally
specifying `--reason` to explain why the working tree is locked.

COMMANDS
--------
add <path> [<commit-ish>]::
Create `<path>` and checkout `<commit-ish>` into it. The new working directory
is linked to the current repository, sharing everything except working
directory specific files such as `HEAD`, `index`, etc. As a convenience,
`<commit-ish>` may be a bare "`-`", which is synonymous with `@{-1}`.
