Improvement: Pass along python interpreter to jedi-language-server (#22466)

Fixes #22495

## Before this PR

Overriding the Python interpreter to a different environment that isn't
the current globally-activated base environment would yield no
completions when Jedi is used as the underlying language server.

Example [stackoverflow
question](https://stackoverflow.com/questions/62018436/vscode-intellisense-code-completion-doesnt-work-when-i-am-not-in-base-conda-e)
hitting the same issue.

## After this PR

We now pass along the interpreter path to jedi-language-server as part
of the initial options under `workspace.environmentPath`
