Subject: [PATCH] build: support git worktrees in sbt-git

The JGit bundled with sbt-git 2.1.0 (5.13.x) cannot read linked git
worktrees (where .git is a file containing 'gitdir: ...') and aborts
project load with NoWorkTreeException. When the build is loaded from
a linked worktree, enable useReadableConsoleGit so sbt-git shells out
to the git CLI for read-only operations instead.

See https://github.com/sbt/sbt-git/issues/264.
