[release/insiders] Source code updates from dotnet/dotnet

[dotnet-maestro]

Caution

This is an unsafe codeflow update ⚠️ Please review carefully as it may contain undesirable changes and/or reverts.
This PR is a self-corrective attempt most likely caused by a recent change in codeflow subscriptions which results in the currently flown branch release/10.0.3xx being divergent from the previously flown branch.

It may contain both source code changes from the VMR
as well as dependency updates. Learn more here.

If the changes in this PR look wrong, you also have the option to reset the VMR's contents to match the repository:

darc vmr reset --build 312133 razor

ℹ️ To resolve the conflicts, please follow these steps:

1. Clone the current repository

   git clone https://github.com/dotnet/razor
   cd razor

2. Make sure your darc is up-to-date
   (version 1.1.0-beta.26227.1 or higher)

   # Linux / MacOS
   ./eng/common/darc-init.sh
   # or on Windows
   .\eng\common\darc-init.ps1

3. Run from repo's git clone and follow the instructions provided by the command to stage the conflict locally

   darc vmr resolve-conflict --subscription ffb0ccf2-e472-42ac-8949-855716f0d527 --unsafe

If you don't care about about the changes made in the VMR, and just want the vmr branch to match your repo you can use

darc vmr reset --build 312133 razor

from the local vmr clone.
This should apply the build 312133 with sources from 7cd99d4
4. Resolve the conflicts, commit & push the changes
5. Once pushed, the Codeflow verification check will turn green.
If not, a new build might have flown into the PR and you might need to run the command above again.
