runtime(dosini): Update syntax script, spellcheck comments only

By default spell checking is enabled for all text, but adding
`contains=@Spell` to syntax rules restricts spell checking to those
syntax rules.  See `:help spell-syntax` for full details.

Variable names and headers are far more likely than comments to contain
spelling errors, so only enable spell checking in comments.
