Add new tag learn-python.md for resources that are often recommended to people just starting out. There are many people looking for resources, often asking for: Youtube, free courses or other learning materials.

The tag content is currently copy pasted as-is from the discord server and needs modifications.

Having a dedicated tag would:

• Give easy access to the commonly recommended resources
• Make it easier to share the specific resources, without necessarily linking to !resources page, and making it confusing to beginners.
• Provide some context to users to understand the resources a little better than just replying !resources

Linking the resources page for more options is still useful, but this tag makes it easier to point to the few specific ones.
