[dnceng-bot] Branch `installer/release/8.0.1xx` can't be merged to Azdo internal branch

Branch [release/8.0.1xx](https://github.com/dotnet/installer/commits/release/8.0.1xx/) in `dotnet/installer` repo can't be mirrored from GitHub to Azure [internal/release/8.0.1xx](https://dev.azure.com/dnceng/internal/_git/dotnet-installer?version=GBinternal%2Frelease%2F8.0.1xx&_a=history) via internal merge.

There are conflicting commits in the target branch.
The branch is configured to be mirrored via automated merge.
The situation is rare but normal. The target branch is expected to receive manual commits in the Azure DevOps clone, which could cause conflict.

Conflicts need to be **resolved to unblock the code flow**.

- you can resolve the issue by resolving the conflict in the **target branch only**.
- Please make sure that the changes sensitive from security perspective are not published ahead of time to GitHub!
- reverting the extra commits in the Azdo target branch.
- checking the logs of the mirroring process in the [mirroring pipeline](https://dev.azure.com/dnceng/internal/_build?definitionId=1387).
- you can disable the mirroring of the branch in the [configuration file](https://dev.azure.com/dnceng/internal/_git/dotnet-mirroring?path=/dnceng-subscriptions.jsonc).
- you can ask @dotnet/dnceng for help or read the [documentation](https://dev.azure.com/dnceng/internal/_git/dotnet-mirroring?path=/README.md).

Please close this issue once the conflict is resolved.

Start by checking the mirroring pipeline logs and the conflict between GitHub branch release/8.0.1xx and Azure target branch internal/release/8.0.1xx. Read the dotnet-mirroring README.md and dnceng-subscriptions.jsonc for the branch configuration. Done means the conflict is resolved in the target branch or extra commits are reverted, mirroring succeeds, and no sensitive changes are published to GitHub.
