fix: allow single character status condition reason

[jmdeal]

Fixes #N/A

Description
This updates the regex validation for the status condition reason on NodeClaims. A previous PR (#1285) updated this regex to allow empty strings and unblock migration from previous versions to v0.37. It also inadvertently changed the regex such that if a string is provided it must be at least two characters. This doesn't have any immediate impact since none of the status conditions are a single character, but this PR corrects the regex.

How was this change tested?
Manual validation
