fix: support table attrs in readme

[alexdln]

Added support for two fields that are supported in other systems but not in our: width and valign for th and td.

• valign is deprecated, but still used
• Also tested width with different values ​​- it works within the container

Closes #1093 (sorry, I missed this part, checked bunch more popular libraries and hopefully we're close to other apps now)

📝 Walkthrough

Walkthrough

This PR expands the allowed HTML attributes in the sanitiser configuration for table elements. Specifically, it adds 'valign' and 'width' attributes to both table header (th) and table data (td) elements in the sanitiser configuration within server/utils/readme.ts. This enables README files to preserve table formatting attributes that were previously stripped during sanitisation.

❌ Failed checks (1 inconclusive)

Check name	Status	Explanation	Resolution
Linked Issues check	❓ Inconclusive	The PR partially addresses issue #1093 by adding table cell attributes (width, valign), but does not fully resolve the issue's broader objectives regarding centred headings, floating images, and other alignment attributes.	Verify whether additional attributes for alignment (align, text-align) and image positioning are required to fully resolve issue #1093, or if this PR represents a phased approach.

✅ Passed checks (2 passed)

Check name	Status	Explanation
Description check	✅ Passed	The pull request description accurately describes the changes made: adding support for 'width' and 'valign' attributes for table cells, with relevant context about deprecation and testing.
Out of Scope Changes check	✅ Passed	The changes are scoped to the readme sanitiser configuration for table cell attributes only, with no unrelated modifications to other files or functionality.
