Add UUID Version & Variant to GenerateGUID description

[TheWandererLee]

Changes

• Added a sentence detailing the Version (4) and Variant (1) of the UUID algorithm used.
  • This was determined by generating a GUID (for example 564c5179-c21c-48e1-b5bb-8bd09f00d3f6) and entering it into a public UUID decoder.
  • I don't believe adding this sentence is of any compromise to security since anyone could publicly do this.
  • This added sentence of information is helpful to note, as this version does not have certain features that other UUID versions have such as encoded timestamps, MAC addresses, or being sortable by time (UUIDv7, ULID).

• Fixed a typo: Extraneous "[" was removed
