Add additional hut23 issue tag

[edaub]

:strawberry: Description/desired behaviour

As part of the REG Dugnad I am going through github repos and checking that they are tagged appropriately. If someone could add hut23-612 to include the third phase of the Safe Haven project I would appreciate it. Thanks!

:page_facing_up: Tasks

• [x] Add additional Github tag hut23-612 to the repository.

:gift: Labels

• type: documentation (really ATI reporting)
• affected: developers (i.e. REG staff)
• severity: minor
