Exclude prior suffix from CLV model config

[wd60622]

The MMM and customer choice models don't have this suffix. All CLV models have this convention. Here is an example:

pymc-marketing/pymc_marketing/clv/models/beta_geo.py

Lines 169 to 172 in d9f0c51

	"alpha_prior": Prior("HalfFlat"),
	"r_prior": Prior("HalfFlat"),
	"phi_dropout_prior": Prior("Uniform", lower=0, upper=1),
	"kappa_dropout_prior": Prior("Pareto", alpha=1, m=1),

I think the "prior" is implied in the context of the model so I find it a bit redundant. Then the variable drops the suffix in the model.

What are your thoughts @ColtAllen?

I think this was done to distinguish between Prior and Posterior TensorVariables because the ModelBuilder prior/posterior methods were unsupported at the time. I'm in favor of standardized API conventions between MMM/CLV/CC, so let's get these variables renamed.
