Feature/key as regex

[nomalord]

Hi,
At my workplace, we use regex matches in tpls to match for values in the root of the values.yaml. I saw the helm-schema doesn't support such a usecase, but since json-schema supports it i decided to implement it myself.

I added a new field to the schema, keyAsPatternProperty that allows matching all keys on the same level to a certain regex pattern (that is provided in the schema)

I struggled a bit in figuring out whether it's better for the field to be boolean (and take the yaml-key as the pattern to match on) or string, but I decided it would probably foot-gun someone to have a mangled key instead of some arbitrary, very unlikely to match key.

Here's and example usage

boolean:

# @schema
# keyAsPatternProperty: true
# @schema
(rabbit|kafka|sqs).*deployment:

string:

# @schema
# keyAsPatternProperty: (rabbit|kafka|sqs).*deployment
# @schema
_:

Thanks in advance 😊

P.S: I see that the README's table changed, but it's only formatting (the only real change is the addition of the keyAsPatternProperty)

I marked this as draft because I didn't add tests yet
