Auto merge of #29014 - yvt:patch/bump-rust-toolchain, r=jdm
chore: upgrade the Rust toolchain to `nightly-2022-10-13` --- - [x] `./mach build -d` does not report any errors (prerequisite: #29009) - [x] `./mach test-tidy` does not report any errors - [ ] These changes fix #___ (GitHub issue number if applicable) --- - [ ] There are tests for these changes OR - [x] These changes do not require tests because they are not functional changes
