Expiration Time is not specified

Problem

We think is worth to add it on the doc. 'NOTE: The maximum time is 'now' + 8000001 seconds (approximately 92 days ).' https://github.com/hiero-ledger/hiero-docs/blob/master/sdks-and-apis/sdks/token-service/update-a-token.md

Solution

Update https://github.com/hiero-ledger/hiero-docs/blob/master/sdks-and-apis/sdks/token-service/update-a-token.md
to include this detail.
