ref(hybrid-cloud): Removes transaction silo routing from patch code

[GabeVillalobos]

With the inclusion of our recent changes to transaction validations in PR #52943 and the inclusion of 'using' in all of our transactions/helpers thanks to PRs #53027 and #53004, we should be able to safely remove the ability to specify a transaction without a using keyword arg.

Because this is now mandatory, it should also be safe to remove autorouting, which ended up being incorrect in many testing contexts anyway.

Love it!

Do we have any transaction.atomic() calls to update in getsentry?

I believe @corps already patched most, if not all of them. Guess we'll find out 😁
