Repository: crazy-max/ghaction-docker-meta (ts)

Issue:
prefix/suffix not working?
### Behaviour

I am unable to add a prefix or suffix in v2 of this action, regardless if specified in the flavor or in the tag attributes.

#### Steps to reproduce this issue

1. Specify `suffix=-dev` in flavor or individual tag
2. Run action
3. Suffix is not applied

#### Expected behaviour

The action should append the suffix to the tag

#### Actual behaviour

The suffix is not appended
