rust-toolchain.toml is no longer recognized

[stinodego]

A recent update seems to have broken this functionality.

This is a recent run (installs stable, ignoring rust-toolchain.toml):
https://github.com/stinodego/polars/actions/runs/6384664783/job/17327784276

This is a slightly older run of ~6 hours ago (installs nightly as specified in rust-toolchain.toml):
https://github.com/stinodego/polars/actions/runs/6380623219/job/17315365326

Maybe it's because of the working-directory specification? Same issue when not using working-directory.

So #213 could have break this.

maturin-action/src/index.ts

Lines 203 to 204 in 3392822

	const manifestDir = getManifestDir(args)
	const rustToolchainToml = path.join(manifestDir, 'rust-toolchain.toml')

We should walk the directories up to $GITHUB_WORKSPACE to find a rust-toolchain.toml instead of just check it once. I don't have time to fix it today, so pull requests are welcome.

Fixed in #217 and published in v1.

Can confirm that this was fixed, thanks!
