Title:
  rustanalyzer cannot find libstd sources for rust-1.82-src

Status in rustc-1.85 package in Ubuntu:
  New

Bug description:
  Hello!

  Looks like there is no sources at the path where rustanalyzer
  searches. I believe that it searches at sysroot/lib/rustlib where
  sysroot is reported by rustc command 'rustc --print sysroot'. It is
  /usr for default rust-all package and /usr/lib/rust-1.xx for
  rust-1.xx-all packages.

  There is no src directory for rust-1.82-src packages.

  $ ls -l /usr/lib/rustlib/
  total 12
  drwxr-xr-x 2 root root 4096 Jan 31 20:14 etc
  drwxr-xr-x 2 root root 4096 Jan 31 20:14 src
  drwxr-xr-x 4 root root 4096 Jan 31 20:14 x86_64-unknown-linux-gnu

  $ ls -l /usr/lib/rust-1.85/lib/rustlib/
  total 12
  drwxr-xr-x 2 root root 4096 Jan 30 17:48 etc
  drwxr-xr-x 2 root root 4096 Jan 31 20:15 src
  drwxr-xr-x 4 root root 4096 Jan 30 17:48 x86_64-unknown-linux-gnu

  $ ls -l /usr/lib/rust-1.82/lib/rustlib/
  total 8
  drwxr-xr-x 2 root root 4096 Jan 30 18:12 etc
  drwxr-xr-x 4 root root 4096 Jan 30 18:11 x86_64-unknown-linux-gnu

  It is minor issue because there are more up-to-date compilers
  available without such problem. For example, rust-1.85-src does not
  have such problem.

  Thank you.
