I propose a workaround, for the moment, based on the solution found by @c-geek: generating a rust-toolchain.toml during the CI process that will match the version normally enforced by srtool.

In the meantime, I have opened https://substrate.stackexchange.com/questions/10958/srtool-cli-no-rust-src-error and will be closely monitoring upstream to see if a fix is available (which I think will take a little time).
