Auto merge of #5672 - phansch:regression-test-env, r=yaahc

Add regression test for `string_lit_as_bytes` issue

Closes #5619

Before the fix in rust-lang/rust#72637, `string_lit_as_bytes` was incorrectly triggering on the `env!` macro. With the fix merged, this test makes sure that the lint is not triggering anymore.
