RA 2021-23-05 can't bootstrap on Windows

[Lokathor]

It looks like some path stuff got messed up on accident.

Note in the ERROR report at the end how it's using a path that's D:\\C:\\, which is clearly always going to be incorrect on windows.

Will be fixed by #8951

As a temporary workaround, downgrading the VSCode extension to version 0.2.599 worked for me:

1. Open the Extensions pannel (View > Extensions, or Ctrl+Shift+X) and select rust-analyzer.
2. Open the dropdown next to the "Uninstall" button and select "Install Another Version..." (see attatched screenshot).
3. Select version 0.2.599.
4. Reload VSCode window (or restart VSCode). There will be a blue button to do this under the rust-analyzer section you selected in setp 1.

A new version which should fix this issue has been published to the Code marketplace.
