Bug: Grammar correction in Core mentorship documentation #1971

Describe the bug

Description

I noticed a small grammatical issue in the "Core mentorship" section of the Python Developer's Guide.

Page: https://devguide.python.org/getting-started/getting-help/

Current behavior

The documentation says:

"Everyone is welcomed and encouraged to contribute."

Expected behavior

The sentence would sound more natural as:

"Everyone is welcome and encouraged to contribute."

Suggested fix

Replace "welcomed" with "welcome" in getting-started/getting-help.rst.

This is a small documentation improvement that would make the sentence clearer for readers.
