Insecure Registry not being set

### Description

I have use colima start --edit to add my insecure registry:
`docker:
insecure-registries:
- 192.168.172.27:6969
- repo.local:6969
- localhost:6969
- 127.0.0.1:6969`

however when i do a docker login, it looks like the insecure registry is not being recognised:
`docker login http://192.168.178.27:6969
Username: admin
Password:
Error response from daemon: Get "https://192.168.178.27:6969/v2/": http: server gave HTTP response to HTTPS client`

Any suggestions?
