Add programming languages usage in 「Learn a Language」

[xchux]

Feature Description

It could be helpful to share current trends in programming language usage to give readers better context. For example:

• Statista: Most Used Programming Languages

• TIOBE Index

Additionally, it's useful to highlight the technology and language requirements for different fields. These can vary by year, so it's a good idea to keep them updated annually. For reference, consider linking to resources like the Stack Overflow Developer Survey 2024.

If it is nice to have, I will create the pull request
