Update environment selection tooltips from "Workspace" to "Project" (#434)

This PR updates the language in the environment selection tooltips to
align with terminology used elsewhere in the extension.

## Changes:
- Changed "Set Workspace Environment" to "Set Project Environment" in
the command title
- Changed "Set As Workspace environment" to "Set As Project environment"
in the command title
- Updated tooltip text from "This environment is selected for workspace
files" to "This environment is selected for project files"

These changes ensure consistency in the UI language, where "Project" is
the preferred term according to the extension's documentation and UI.

Fixes #328.
