Not warning about the lack of rust-analyzer

Lapce Version

0.2.4

System information

Arch Linux kernel version: 5.15.81-1-lts

Describe the bug

Autosuggestion not working when dealing with some crates (In Rust)

Syntax highlighting just not showing in some cases

The problem?

I fixed it, it was that rust-analyzer was not installed.

The problem with that?

I only found out when I was trying to switch to Helix,
and had to install rust-analyzer via rustup and do a symlink to a directory in PATH from the analyzer binary.

What I suggest?

Adding a prompt warning about the lack of rust-analyzer like other mainstream IDE's instead of just being silently faulty.

Or even installing it automatically.

I had no idea what was wrong with the Rust plugin, I thought the 'sub-par' (Used lightly) performance of its highlighting was 'normal', until I added the missing part by accident and made it work like a champ!

I can now use Lapce coding in Rust without reservation and have had a fantastic experience so far, keep it up!
This is a wonderful project that was badly needed (The Rust plugin was needed too :P).

I just want other people coming to Lapce for a good Rust environment not be discouraged by its problem when it lacks rust-analyzer.

I made this issue since I think this is something that should me made aware to the user.

No files, tests, or entry points are named. Start by locating the Rust plugin's initialization and its handling of rust-analyzer availability; compare the requested warning with the alternative of automatic installation. Done should include a clear user-facing response when rust-analyzer is missing and coverage for that condition.
