Add UrlFormat to ObsoleteAttribute for ASPDEPR diagnostics (#63909)

Copilot · joperezr · web-flow · commit 9f255d1ed217 · 2025-10-13T14:38:12.000-07:00
* Initial plan

* Add UrlFormat to all ASPDEPR obsoletions

Co-authored-by: joperezr &lt;13854455+joperezr@users.noreply.github.com&gt;

* Use Obsoletions.AspNetCoreSharedUrlFormat constant for all ASPDEPR UrlFormat references

Co-authored-by: joperezr &lt;13854455+joperezr@users.noreply.github.com&gt;

* Fix UrlFormat to use numeric diagnostic IDs instead of full ASPDEPR IDs

Co-authored-by: joperezr &lt;13854455+joperezr@users.noreply.github.com&gt;

* Remove unnecessary reference to Obsoletions.cs in the project file
