Updates virtualenv docs page #2

[kevin-dimichel]

Rationale

In PR #92, @Burhan-Q contributed some improvements. In PRs #87 and #94, we moved files around. This affected #92. To preserve the contributions and not make the community contributor perform the chore of rebasing of main, I checked out the PR (as recommended by @thesteve0) using

git fetch origin pull/92/head:kevin/Burhan-Q-venv-update

rebased off main, and fixed the pre-commit violation.

Below is a copy/past from #92:

Splitting out changes introduced in #30 specifically for docs/getting_started/basic/virtualenv.md page.
