Where possible, convert GitHub links in roundup pages to internal Hub links

Background

When earlier Roundup pages were imported to the hub, someone went through manually converting GitHub links to hub links.

For example:

• This on the hub: 2021-07-03: Sync Updates, URI improvements, & workflows
  • contains the [[initiative-tracker|Initiative Tracker]] plugin ...
• Whereas the original page 2021-07-03: Sync Updates, URI improvements, & workflows:
  • contains the [Obsidian Initiative Tracker](https://github.com/valentine195/obsidian-initiative-tracker) ...

Linking to Hub's plugin or theme note is a bit more useful for users, as those notes are more feature-rich than just going directly to the GitHub page.

Recently, we have been importing Roundup pages with no curation (which is fine) - so all links are retained, as-is.

Suggestion

Where a GitHub repo URL in a roundup page matches the URL in a plugin or theme note, we could replace the link so that the roundup page instead links to the corresponding note instead.

When roundup articles are processed initially, they often refer to plugins or themes being reviewed and not yet officially approved, and therefore not yet having pages in the Hub.

Therefore this would be more effective if it could be run retrospectively on existing roundup hub pages.
