Fix "[main] Update Package Versions" job failing with merge queue enabled

[Copilot]

The scheduled [main] Update Package Versions job exits with code 1 even after successfully opening its automation PR. With the repository's merge queue enabled, gh pr merge --delete-branch is rejected, failing the step:

X Cannot use `-d` or `--delete-branch` when merge queue enabled
##[error]Process completed with exit code 1.

Change

• build/scripts/AutomatedSubmission.psm1: drop the incompatible --delete-branch flag from the auto-merge call.

- gh pr merge --auto --squash --delete-branch | Out-Null
+ gh pr merge --auto --squash | Out-Null

Head-branch cleanup is governed by the repo's "automatically delete head branches" setting, so behavior is unchanged for merge-queue merges.
