fix: Prevent auto-linking when typing URL inside inline code mark

[rfgamaral]

Please describe your changes

At Doist we have extended the Code extension to allow all marks (e.g., Bold, Italic, and Strikethrough) to coexist with the Code mark, which gives a behaviour that more closely resembles GitHub, allowing us to render inline code marks with formatting and links, like this: Typist.

However, this created an issue for us, where URLs typed inside inline code marks were automatically converted into links, which is not the behaviour we want. Here's a demo of our own editor based on Tiptap exhibiting the issue:

CleanShot.2023-06-22.at.22.54.59.mp4

How did you accomplish your changes

Added a filter rule to the autolink helper where we check if the detected link being typed is inside a code mark, if it is, we discard it.

How have you tested your changes

Manually by bringing the autolink.ts file into our own editor and our own extended Link extension with the changes proposed in this PR.

How can we verify your changes

Tweak the editor running on Tiptap's homepage to run the Code extension without excluding all other marks (ref), and to use the changes proposed here. Then try something similar to demo above.

Checklist

• The changes are not breaking the editor
• Added tests where possible
• Followed the guidelines
• Fixed linting issues
