docs: fix spelling errors and standardize time notation in documentation #27851
Description
Description
Spelling errors:
In RELEASE.md:
there's a typo where "abbrieviated" is misspelled. It should be "abbreviated".
In ISSUE.md:
"repoducer" should be "reproducer" (occurs twice in the document)
"UT" (Universal Time) should be standardized to "UTC" (Coordinated Universal Time), which is more commonly used and precise in technical documentation.
