Auto merge of #116450 - Kobzol:automation-try-bors-ci, r=Mark-Simulacrum

Enable new bors try branch to run on CI

Needed to fix [this error](https://github.com/rust-lang/rust/actions/runs/6420044833/job/17431256956). Inspired by rust-lang/rust#99988

Also, removes `try-merge` from the workflow. It shouldn't have been added in rust-lang/rust#116353.
