Wrong values accepted for queryables only found in form

[anesson-cs]

Describe the bug
The value of a queryable is set as its default value even if it is not allowed. We can get this case when a parameter is neither in default parameter of the product type configuration of a provider nor in a potencial constraints file of the provider. We can then find this parameter in a queryables form, and values of this parameter are already taken in eodag in values variable in queryables_by_form().

Code To Reproduce
In ERA5_PL default parameters configuration of cop_cds configuration, remove "ecmwf:download_format": zip. Then, run the following code:

queryables = dag.list_queryables(
    productType="ERA5_PL",
    provider="cop_cds",
    fetch_providers=True,
    **{"ecmwf:download_format": "unarchivedddd"},
)
print(queryables["ecmwf:download_format"])

Output
typing.Annotated[typing.Literal['unarchived', 'zip'], FieldInfo(annotation=NoneType, required=False, default='unarchivedddd', title='Download format', description="If you select 'Zip' the files will always be zipped into a single file. <br><br> If you select 'Unarchived' then the files will be returned unzipped if there is only one file, and zipped if there are multiple files. <br><br> Please note that in some circumstances the conversion from GRIB to NetCDF can result in multiple files.")]

Environment:

• Python version: 3.12.3
• EODAG version: 3.0.0b4.dev121+g7c92c3a7

Additional context
A avenue to go throught this issue is:

# check if default value is allowed
if (default := defaults.get(name)) and default not in values:
    raise ValidationError(
        f"ecmwf:{name}={default} is not allowed. "
        f"Allowed values are {', '.join(values)}."
    )

values variable may be a list containing the values needed (for exemple for year queryable), then a processing of this variable has to be done.
