Link to "encrypted secrets" GitHub Docs

[felipeelia]

Describe the bug

Probably GitHub has updated their docs and the Secrets are set in your repository settings link present on the README.md file points to the wrong page.

Steps to Reproduce

1. Go to repo's README.md
2. Click on Secrets are set in your repository settings.
3. The link points to the Virtual environments for GitHub-hosted runners page but the related section isn't there anymore :(

Expected behavior

The link should point to this new page.

Welcome to our GitHub Actions and thanks for the report @felipeelia! Mind making the same update to the https://github.com/10up/action-wordpress-plugin-asset-update repo as well?

[felipeelia]

Thank you @jeffpaul! I'm happy to (modestly) retribute the effort you folks put on it. I've opened a PR with the same fix there as well. Let me know if there is something else where I can help, ok?

[jeffpaul]

@felipeelia there's some "help wanted"+"good first issues" scattered across 10up's repos, but if there's one of our projects or a type of work you're most comfortable with I'd be happy to dig some more specific items up... just let me know!

[felipeelia]

I'll give a look, for sure! Thanks once more @jeffpaul
