docs: fix Microsoft.Foreign hits (e.g./i.e. -> for example/that is)

Substitutes 'for example' for 'e.g.' and 'that is' for 'i.e.' per
Microsoft style, with no comma after the replacement -- this repo
never puts a comma after e.g./i.e. either, so the substituted phrase
matches that house style instead of vale's literal 'for example,'
suggestion.

Covers all 77 real hits (72 from the initial vale pass + 5 more of the
same pattern found on a follow-up vale run). None of the flagged
instances were sentence-initial, so there's no capitalization concern
here.

Verified via a fresh vale run: 0 remaining Microsoft.Foreign hits.
Full accounting in /agents/iris/state/haiku-batches/foreign-report.md.
