Allow to set versions of Python tools

[SKairinos]

When using the official python feature, you can specify which tools to install BUT not the version of those tools. Please add the ability to set version numbers.

You use ":" as a delimiter.

{
"toolsToInstall": "black:1.1.1,pipenv:2.2.2"
}

Hi @SKairinos

It seems that specifying the package version is already supported. You can use == as the "delimiter"

For example, this devcontainer.json will provide you devcontainer with black and pipenv in the specified versions:

{
	"name": "Debian",
	"image": "mcr.microsoft.com/devcontainers/base:bullseye",
	"features": {
		"ghcr.io/devcontainers/features/python:1": {
			"toolsToInstall": "black==24.4.2,pipenv==2024.0.1"
		}
	}
}
