- Fixed test name, it should've been `rustc_bootstrap.rs`, oops. - Slightly reworded test comment to make it more clear.

There was a problem hiding this comment.
The dist version extraction above this is slightly hacky, and so is this, but oh well.

Fixes #133503.
Previously,
tests/ui/bootstrap/rustc_bootstap.rs[sic] failed during beta bump in opt-dist tests. This is because:opt-disttried to run./x testagainst beta-channel distrustcthroughbootstrap.rustcwhich correctly thinks that it is a beta compiler based onsrc/ci/channelinfo.opt-disttries to run./x teston the betarustcfrom the dist build, but without specifying channel through a syntheticconfig.toml, sobootstraptellscompiletestthat we're on thenightlychannel (by default).compiletestbelieves therustcunder test is a nightly rustc, but therustcunder test actually considers itself a beta rustc. This means that//@ only-nightlywill be satisfied yet the test will fail as the beta rustc is not a nightly rustc.This PR:
tests/ui/bootstrap/rustc_bootstap.rsfails in post-PGO/opt-dist tests #133503) by havingopt-distfaithfully report the channel of the distrustcbeing tested (i.e. "beta" in a beta bump PR). This will properly make the test be ignored during beta bump as therustcunder test is not a nightly rustc.rustc_bootstap.rs->rustc_bootstrap.rs. No more stapping.I ran a try-job against the beta branch (explicitly running the opt-dist tests by modifying the job definition) with these changes in #134131, and it appears that the try-job was successful. The two commits in this PR are cherry-picked from #134131, with the test commit slightly modified (to also adjust the test comments).
