docs: fix typos and a few grammar issues (ported from #1852 RST → MyST)

Ports the typo/grammar sweep originally captured in PR #1852 from .rst
files to their .md equivalents, plus the eventhandler grammar fix that
Copilot flagged in #1852's review (which the RST PR explicitly skipped
as scope-stretch).

Sources:
- 73 typo/grammar substitutions from PR #1852 (rebased from #1801)
- "Using environments is more preferable" → "Using environment variables
  is preferable" (Copilot review comment on #1852)

#1852 itself is being discarded since it targets RST and we are phasing
out the RST tree in favor of MyST.

The 4 RST-linter line-wrap comments and 1 RST section-underline comment
from Copilot's #1852 review are RST-specific and do not apply to .md.
