alr publish does not work anymore in a git submodule #1021
Description
The alr publish was working well when running in a git submodule.
This is not the case anymore at its crashes:
ciceron@zebulon:/src/awa/ada-awa/ada-util$ alr -d publish
✓ Local repository is clean.
ⓘ Crate at /src/awa/ada-awa/ada-util is nested in repo at /src/awa/ada-awa/.git/modules/ada-util

error: directory "/" has no containing directory
error: alr encountered an unexpected error, re-run with -d for details.
The root cause is the commit 26c5c28 which introduced the Get_Rel_Path_Inside_Repo function that now fails.
I think the logic behind its use is not correct because for a submodule, you will get a different path:
ciceron@zebulon:/src/awa/ada-awa/ada-util$ git worktree list
/src/awa/ada-awa/.git/modules/ada-util 2def17d [master]
and the git repository is not in the same sub-tree as the sources.
The old logic in alr 1.1 is working very well.
