• Added support for optional timezone argument in the parse_timestamp function.

An explicit timezone should not be required:

• tracing_rs: contains the offset
• OPA: always in UTC
• Python: in local time without a zone or offset, but parse_timestamp assumes local time by default (https://vector.dev/docs/reference/configuration/global-options/#timezone).
• Airlift: always in UTC
• log4j and log4j2 use the Unix timestamp.
