ToBeEmpty assertion in jest-extended collides with jest-dom's one

[DanielaValero]

Describe the feature you'd like:

Jest-Extended has an assertion named the same as jest-extended's one:

-> https://github.com/jest-community/jest-extended#tobeempty -> https://github.com/testing-library/jest-dom#tobeempty

When both libs are used in the same project, in my case the version of jest-extended overwrites the one from jest-dom. But this might vary depending on the order used to add the libs

Describe alternatives you've considered:

Maybe an option is to add an alias for toBeEmpty named toBeEmptyValue or something ?

Teachability, Documentation, Adoption, Migration Strategy:

I am not sure at this moment how the things work, could it be an option to have 2 names for the same assertion?

If yes, then the documentation could say: "if you are using jest-extended, then use toBeEmptyValue" or something like this

However, I have raised a feature request in Jest Itself asking for a feat that warns the user about the name collision and points out to a link where is documented a way to rename one of the colliding names in the project where the situation happens.

https://github.com/facebook/jest/issues/9678

It could be that the warning and the documentation of how to solve it in projects, might be enough to address this and similar situations like this one.
