Always use environment path when running conda environment commands (#24807)

Attempt at fixing
#24585

There are many edge scenarious where refering to the name of the
environment rather than the path can cause breaks in the extension. Some
examples

1 -**If we have two anonymous environments with the same name in
different folders**

/path1/my-env
/path2/my-env (where my active vscode python interpreter is)
by using conda -n my-env it'll always use the first env.

2 - **Some times people avoid actually activating their conda envs when
using conda-pack** https://github.com/conda/conda-pack

This is because the activation scripts are known to be flaky and not
very reliable

3 - **The environment may have been created by a conda-compliant
replacement**

Therefore conda itself is not aware of it by name but can work with it
properly using the path. This is the case of
[hawk](https://community.palantir.com/t/introducing-hawk-for-python-package-management-in-code-repositories/500)
or frankly anyone building their own conda package manager on top of
[rattler](https://github.com/conda/rattler).


Some of these points are also hinted at
#24627 (comment)
, and supported by a conda maintainer in
#24585 (comment)

This PR has a minimal attempt at changing that by always forcing -p
usage
