fix: make regex for hosts consistent with APISIX

[Revolyssup]

Type of change:

Fixes #2064
Currently there is a mismatch between the regex that APISIX allowed[1] and what ApisixRoute CRD allowed. This PR makes sure that both are consistent.
More specifically - Both 1.2.3.4 and 1.2.3.4:443 should be considered valid hosts field

   "pattern": "^\\*?[0-9a-zA-Z-._\\[\\]:]+$",

Is there a problem with the admin-api mode?
We need test cases to cover it.

The admin api is fine. The regex of the same field that admin api expects and what ingress controller expects is different. So this PR makes sure that regex is same for the same field.
Okay I'll add a test case.

This issue needs to be fixed first for the CI to pass here api7/lua-resty-radixtree#138

[AlinsRan]

Does this use case seem unrelated to PR? What about the port?
