Issue summary

I just came across this in a v13 install. I believe I wrote some custom code using EPPlus before adding Forms to the project. I'd installed EPPlus V7. Installing the Forms package don't validate the EPPlus version, but all EPPlus versions from and above v5 is backwards incompatible with the Forms Export to Excel feature. They all throw exceptions about missing methods.
I see that the Forms nuget package requires EPPlus >= 4. It should rather specify 4.* or [4.0.0, 5.0.0) explicitly so we get a report that Forms is incompatible with later versions of EPPlus.

Specifics

No response

Steps to reproduce

Install EPPlus >= 5.* before installing forms and then try to export forms from the BO.
