v0.20.0 is released as stable instead of beta

[slavovthinks]

Describe the bug
Im migrating to ormar and I was trying to run the examples from the docs but I was getting AttributeError: 'ModelMetaclass' object has no attribute 'ormar_config' as well as AttributeError: 'MyModel' object has no attribute 'ormar_config'. I was unable to figure out what is the problem so I tried lowering the version of ormar which fixed the issue.

I went to GH and I saw that v.0.20.0 was released as a stable version instead of beta.

To Reproduce
Steps to reproduce the behavior:
1. pip install ormar or pip install --upgrade ormar

Try to define you model like this

base_ormar_config = ormar.OrmarConfig(
    database=database,
    metadata=sqlalchemy_metadata,
)

class Example(ormar.Model):
    ormar_config = base_ormar_config.copy(tablename="example")
    ...
    # other fields

Yeah this should definitely be in the beta channel.

Hmm I thought it was released as beta, at least that's what I checked during creating of the release, will try to check it out tomorrow
