[RFC] Add as_dict alias to to_dict for DynaBox for consistency between LazySettings and DynaBox objs

[mitches-got-glitches]

Is your feature request related to a problem? Please describe.
It's possible to convert a LazySettings object to a Python dictionary with LazySettings.as_dict(), and there is an alias to to_dict for backwards compatibility. The DynaBox class inherits from the Box class which comes from a vendor. There is the method Box.to_dict()
but not .as_dict(), so there is an inconsistency for the user if the user accesses a sub-box of settings and then tries to convert to a dictionary - see context.

Describe the solution you'd like
Add an alias to DynaBox:

class DynaBox(Box):
    ...
    as_dict = to_dict

The opposite of what is done here:

dynaconf/dynaconf/base.py

Line 424 in 4ab5183

to_dict = as_dict # backwards compatibility

Describe alternatives you've considered

No	Alternative	Drawback
1	Using a combination of as_dict() and to_dict()	confusing for the user
2	Using to_dict() for both LazySettings and DynaBox	seems like this is the older method and the current guidance is to use as_dict()
3	Doing only LazySettings.as_dict() and then using keys to get to dict level we want	takes away the flexibility of using dot notation to get to sub-levels of config

Additional context

nested_settings.toml

[hyperparameters]
max_depth = 10
n_estimators = 20

Examples

from dynaconf import Dynaconf
settings = Dynaconf(settings_files=['nested_settings.toml'])

print(settings.as_dict())
>>> {'HYPERPARAMETERS': {'max_depth': 10, 'n_estimators': 20}}

print(settings.hyperparameters.as_dict())
>>> dynaconf.vendor.box.exceptions.BoxKeyError: "'DynaBox' object has no attribute 'as_dict'"

print(settings.hyperparameters.to_dict())
>>> {'max_depth': 10, 'n_estimators': 20}

This looks reasonable to me.
Cant see why not.
