Description

This PR adds support for the phpDocumentor tool via the tools input to setup-php.

phpDocumentor has also been aliased to phpdoc for convenience.

I have added a test to the linux test for the base name and to the darwin test for the alias.
👉🏻 Should I also add a test to the windows test ?
👉🏻 Should I add a test for downloading different versions ?

In case this PR introduced TypeScript/JavaScript code changes:

• I have written test cases for the changes in this pull request
• I have run npm run format before the commit.
• I have run npm run lint before the commit.
• I have run npm run release before the commit.
• npm test returns with no unit test errors and all code covered.

Note: running these scripts, automatically added two unrelated changes to the PR, which I have manually removed (had to disable the pre-commit hook to do so). The changes were to package-lock.json and to dist/index.js. Not sure what's going on there.

In case this PR edits any scripts:

• I have checked the edited scripts for syntax.
• I have tested the changes in an integration test (If yes, provide workflow YAML and link).

Do not worry about the changes in package-lock.json and dist/index.js. They could be because of different node or npm versions on my machine from yours. You can let them be in the PR as I update all the dependencies before the release and these files are updated.

One test for the latest is fine.

The PR is perfect. Merging it
