If there is a Pipfile or .python-version file, trigger discovery when autoselecting

[karrtikr]

THIS ISSUE MAY NOT BE NEEDED ONCE WE HAVE WORKFLOW EXTENSIONS MANAGING THEIR OWN ENVS: #22836

When opening a new workspace, before auto-selecting begins:

• If there is a Pipfile, make sure to trigger Pipenv discovery:
• If there is a .python-version file, make sure to trigger Pyenv discovery

This is where we should do it:

vscode-python/src/client/interpreter/autoSelection/index.ts

Lines 207 to 209 in b9109cf

	await this.interpreterService.triggerRefresh({
	searchLocations: { roots: [resource], doNotIncludeNonRooted: true },
	});
