fix(.github/workflows): remove unexpected inputs from gemini-cli workflows (#4671)

The github_pr_number and github_issue_number inputs are removed from the
with section of the google-github-actions/run-gemini-cli@v0 action in
.github/workflows/gemini-invoke.yml and
.github/workflows/gemini-plan-execute.yml.

These inputs are not supported by the action and were causing
"Unexpected input(s)" warnings during workflow runs.

Fixes #4668
