FYI, the best way to self-test an action is to make a local checkout in the job and call it through a relative path. Here's an example: https://github.com/ansible-community/ansible-test-gh-action/blob/d397b87/.github/workflows/test-action.yml#L144.

name: "Python Dependency Installation"
description: "Install Python dependencies from requirements.txt file"
inputs:
path: # id

Instead of removing old input names, it's best to use a deprecationMessage (with this setting, GitHub hints end-users to update gracefully, whenever they run your action) like I did here: https://github.com/pypa/gh-action-pypi-publish/blob/79739dc/action.yml#L12-L23. Of course, this requires a bit of logic elsewhere, to use the old value as a fallback.

await exec.exec(`python -m pip install -r ${requirementsPath}`);
} else {
await exec.exec(
`python -m pip install -r ${requirementsPath} -c ${constraintsPath}`

It's best to use an env var for this, since pip doesn't bypass constraints to internal ephemeral envs made for building sdists via PEP 517.

Suggested change
`python -m pip install -r ${requirementsPath} -c ${constraintsPath}`
`PIP_CONSTRAINT='${constraintsPath}' python -m pip install -r ${requirementsPath}`

(not sure if this syntax works in JS, you may need to figure out how to pass env vars in a different way...)
