Maximum Value Exceeded

[Salacas]

Describe the bug
The default value of DecimalFields in update or create methods exceeds the maximum value, given by the arguments "max_digits" and "decimal_places" in Django's DecimalField, resulting in error responses unless the values are modified by hand.

To Reproduce
We take 'depth' field in 'Earthquakes' model:

When we generate the schema, the default values for post (or put, patch, etc.) method are:

The default value of 'depth' exceeds the limit by 1, as shown in the response:

Expected behavior
Default value of 'depth' should be 1 x 10 ^ 99 (or any value between the accepted range)
I took a look at the code, and found a possible fix.
In the following file:
https://github.com/tfranzel/drf-spectacular/blob/master/drf_spectacular/openapi.py
changed line 814 from:
value = 10 ** field.max_whole_digits
to:
value = 10 ** (field.max_whole_digits - 1)

That seems to resolve the problem. However, some tests failed with this change.
