chore: replace all U+00A0, the non-breaking space (NBSP) with a regular space

[davidsbatista]

Proposed Changes:

• Replaced all non-breaking spaces (U+00A0, \xc2\xa0) with regular spaces across 103 docs files.
• These characters are visually identical to regular spaces but cause issues with search indexing, text processing scripts, and copy-paste behavior for readers.
• They typically sneak in when content is copied from Google Docs, Notion, Confluence, or Word.

How did you test it?

• grep -rl $'\xc2\xa0' docs/ before and after — 103 files affected, 0 remaining.

Notes for the reviewer

• Pure whitespace substitution, no content changes.
• I just discovered this because PyCharm renders them and distinguish them from regular white spaces
