Include props for contributors from other related pull requests

[desrosj]

Problem

Currently, the bot pulls in:

• Contributors to the current PR.
• Contributors to any issues linked to the current PR.

It's not uncommon for there to be multiple attempts to fix one issue. However, PRs can only be linked to issues, and issues to PRs.

For an example, both WordPress/gutenberg#58713 and WordPress/gutenberg#58645 attempts to fix WordPress/gutenberg#58628.

WordPress/gutenberg#58713 was ultimately the fix that was merged, but the contributors to WordPress/gutenberg#58645 also deserve to be included for attempting to solve the problem.

Feature Request

The bot should be updated to also include contributors to any other pull request linked to linked issues.

Workaround

The only current workaround is to manually include them.
