The word `submission` is misspelled as `submittion`

[eecavanna]

It's near the end of this line:

docs/content/home/src/howto_guides/submit2nmdc.md

Line 72 in 20f9d04

Permission roles are granted by ORCID provided and are as follows: Viewer, will have permission to view the entire submission, and cannot make any edits; Metadata Contributor, will have permission to view the entire submission, and can edit **only** the sample metadata section of the submission; Editor, will have full view and edit access to all parts of the submission, **except** contributors; none, no permissions or view granted. The Principal Investigator will be granted the same permissions as the submittion and **can edit the entire submission**.

This misspelling was reported by a spellchecker (under construction) in the docs repo.
