chore: upgrade Rust to 1.54.0

Upgrades Rust to 1.54.0 and applys clippy's fixes.

@kt3k I don't know if you know, but it seems that somehow the upgrade to Rust 1.54 causes us to run out of disk space on CI on Windows. I suspect it is something to do with our build caches, but I don't know enough to "fix" it.

[kt3k]

'Post Clone repository' step says There is not enough space on the disk. : 'D:\a\_temp\_runner_file_commands\set_env_b44b1bfe-1ffe-40fd-8e4d-37c9df5dd52d', but I think that step only does clean-ups. So I doubt we actually run out of disk space..

'Test release' step shows Error: thread 'basic' panicked at 'assertion failed: build_plugin_output.status.success()', test_plugin\tests\integration_tests.rs:21:3. I guess that one would be the actual problem we need to address

I'll rerun CI anyway

@kt3k yeah, I re-ran CI already and it continuously fails with the same error... 😕
