Rollup merge of #116245 - flip1995:clippy-backport, r=Manishearth

Clippy backport: Move needless_raw_string_hashes to pedantic

Really small backport this time. Context: rust-lang/rust-clippy#11415 (comment)

I'd rather get this in 1.74 than waiting another release cycle.

r? `@Manishearth`

cc `@Mark-Simulacrum` This should be merged before beta is branched tomorrow.
