updating lib using git tag did not work

• [X ] I have searched the issue tracker and believe that this is not a duplicate.

Make sure you run commands with -v flag before pasting the output.

Steps to reproduce

pdm init
pdm add git+ssh://git@github.com/benjaminp/six.git@1.11.0
pdm run python -c "import pytest; print(pytest.__version__)"

pdm add git+ssh://git@github.com/benjaminp/six.git@1.12.0
# or manually edit pyproject.toml and do a pdm update

pdm run python -c "import pytest; print(pytest.__version__)"

Actual behavior

it still shows 1.11.0 after the update

updating a lib (six, eg) though git tag sucessed without error, except it did not update the lib

Expected behavior

it should update the lib to new git tag

As a workaround you can include the package name in the requirement:

pdm add "six @ git+ssh://git@github.com/benjaminp/six.git@1.12.0"

Or run another pdm sync can also work.
