Pull request overview

This PR updates Fabric region availability documentation to reflect that Fabric User Data Functions are now available in Canada East, and reindexes the remaining feature footnotes accordingly.

Changes:

• Removes the Canada East footnote marker that previously indicated a feature limitation.
• Removes the “Fabric User Data Functions” limitation footnote entry and renumbers remaining footnotes.
• Updates all affected superscript references in the “All workloads” region table to match the new footnote numbering.

[Copilot]

The UDF footnote was removed from this region table, but other docs still state that User Data Functions aren't available in a subset of regions and direct readers here for the up-to-date list (for example, docs/data-engineering/user-data-functions/user-data-functions-service-limits.md under "Regional limitations for User Data Functions"). Either keep a footnote/list here for UDF regional availability (updated for Canada East), or update the UDF docs to stop referencing this page for that list so the docs remain consistent.

Suggested change

	<sup>5</sup> [Plan (preview)](../iq/plan/overview.md) isn't available in these regions.
	<sup>5</sup> [Plan (preview)](../iq/plan/overview.md) isn't available in these regions.
	<sup>6</sup> [User Data Functions](../data-engineering/user-data-functions/overview.md) have region-specific availability. For the current list of supported regions, see [User Data Functions service limits](../data-engineering/user-data-functions/user-data-functions-service-limits.md).
