docs: update Run_MaxText_via_multihost_runner.md

[eltociear]

minor fix

[evdcush]

FYI this user, eltociear, makes trivial/vapid diffs to documentation in any trendy or recently public repo related to AI on github to feature in the contributors.

For example:

• "Github" --> "GitHub"
• "Huggingface" --> "Hugging Face"
• "an" <--> "a"

or other inconsequential (spellcheck at best) diffs, to be a "contributor".
