Render the parameter of a conditional always as select

[bernt-matthias]

For a long time we have a linter role and IUC guideline that requires tool authors to make the conditional parameter a select (ie. forbid boolean select parameters).

Changing these parameters from bool to select requires downstream changes (workflows).

It might be better to just render boolean conditional paramaters as select even if the tool form specifies it as boolean.

Discussed in dev meeting -- we would like to push back to the IUC with this to understand why this is a requirement. Potentially reduce the lint from warning to info if this isn't actually critical to adhere to.

Need to understand if this is more of a galaxy-side UI standardization request or something else.
