Update 08-security-considerations.md

Add missing "t" to "untrusted"

Good catch! However, this needs to be edited in docs/docs/08-security-considerations.md instead of the versioned ones. Otherwise the typo will come back in the next version.

Ah I see! I have made the same change in docs/docs. I assume that leaving the change in the first file is harmless since a) it is a correction and b) that it will get overwritten anyways.

Let me know if there is anything else, and apologies for missing the versioning scheme

Thank you!
