RFR: 8342886: Update MET timezone in TimeZoneNames files [v5]

[Gautham Krishnan]

> MET timezone entry in TimeZoneNames.java and TimeZoneNames_*.java needs to be updated as MET is alias to Europe/Brussels as per 2024b tzdata changes.
> 
> Also Bug4848242.java needs to be removed as the test expects all euro locale time zones should have the same short names.
