Describe your changes
Docs builds broke after merge of [0], not because its settings were incompatible, but because its inclusion of a
rust-toolchain.toml
file busted the CI cache, and caused themdbook
dep to be freshly installed, rather than retrieved from cache. We don't version-lock mdbook and friends, and the latest version evidently bumped MSRV to 1.74, which is newer than what we set for MSRV. We should probably bump MSRV too, but I'll do that separately. This commit is to unbreak the docs builds.[0] #4145
