Use the latest rust-analyzer related crates.

The enum ra_ap_project_model::ProjectWorkspace had been refactored at the version v0.0.212 against v0.0.211.

v0.0.211: https://docs.rs/ra_ap_project_model/0.0.211/ra_ap_project_model/enum.ProjectWorkspace.html
v0.0.212: https://docs.rs/ra_ap_project_model/0.0.212/ra_ap_project_model/struct.ProjectWorkspace.html

Seems here exists some clippy errors 😮.

Could I fix them by following the clippy's suggestions?

Seems the ToString impl check events are added from rust v1.78.0. 🤣.

Would you mind rebasing this onto main with linear history?

let me create a new branch and new PR...

I don't know why it cannot process on rebase operation...

'Cause nearly I havn't used the rebase operation in the working life, I only used the merge operation('Cause we need to record the meaningful branch name with jira-or-something on the commit message).

So I'm afaid to forcibly do something with currently-unfamiliar rebase operation and let your main branch graph or history be chaos, so I decide to create a new branch which is checked out from the upstream/main and rise up a new PR.

I will deep dive into learning the rebase operation latter.
