`poetry add` doesn't work with `git+file:///` URLs (... | python-poetry/poetry

Nobody has claimed this yet.

Poetry version: 1.3.1
Python version: 3.11.1
OS version and name: Debian bookworm (12)
pyproject.toml: NA

I am on the latest stable Poetry version, installed using a recommended method (pipx).
I have searched the issues of this repo and believe that this is not a duplicate.
I have consulted the FAQ and blog for any relevant entries or release notes.
If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

Issue

poetry add with git+file:/// URL of local git repository results in error: Could not parse version constraint: ///tmp/tmp.AcoK44cpew/prj1@main.

Reproduce with:

_tmp="$(mktemp -d)"
pushd "${_tmp}"
poetry new prj1
poetry new prj2
_branch='main'
git -C prj1 init --initial-branch "${_branch}"
git -C prj1 add --all
git -C prj1 commit -m 'initial commit'
cd prj2

# poetry fails to add the project from file:/// URL
poetry add "git+file://${_tmp}/prj1@${_branch}"
# => error: Could not parse version constraint: ///tmp/tmp.AcoK44cpew/prj1@main

# pip install works just fine
poetry shell
_branch='main'
pip install "git+file://${_tmp}/prj1@${_branch}"
# => ...
# => Successfully installed prj1-0.1.0

The documentation doesn't claim that git+file:/// URLs are supported. So maybe this is a feature request. But since pip/setuptools has no issue with it, poetry should probably support it, too.

Output of poetry -vvv add "git+file:///tmp/tmp.AcoK44cpew/prj1@main"

Start by reproducing the command, then trace the entry points mentioned in poetry/console/commands/add.py and init.py into poetry/core/factory.py, dependency.py, and constraints/version/parser.py. Done means a local git+file:/// dependency can be added without the version-constraint error and the existing reproduction succeeds.
