[infra] Add page feedback form

[theletterf]

Desired feature or idea: What would you like to see happen?

As discussed in the last SIG meeting, we'd like to add Docsy's feedback widget and repo link (create issue) to our site:

• https://www.docsy.dev/docs/adding-content/feedback/#user-feedback -
  Enable page-feedback form for doc pages #4772
• https://www.docsy.dev/docs/adding-content/repository-links/

Thanks @theletterf for creating the issue. I suggest tackling the subtasks separately.

@chalin Seems like repo links appeared automagically after #4772 got merged!

We'd consider customizing the icon or the issue title text though -- just the title seems overly basic to me.

I wonder if we could combine that feedback form with a github issue form. I played with them for the community repo a while back and they allow you to provide a more structured issue creation, i.e. you can make things mandatory or provide input fields, etc. WDYT?

[chalin]

Hmm, I like that idea!

Cross-referencing a relevant Docsy issue:

• Page feedback improvements google/docsy#2054

Given the discussion in https://cloud-native.slack.com/archives/C06EDFPQ5EH/p1724142213551189, I've created the following issue and reexplained why this hasn't been implemented yet:

• [infra] Page feedback create-issue link should include page title, URL path, and source URL, if possible #5091

Closing this issue now since the website has page-feedback forms enabled. Adjusting the issue title, etc., is in scope of #5091.
