fix(eslint-plugin): [no-base-to-string] soft remove ignoreTaggedTemplateExpressions option

[LinusU]

ref: #1914

This "soft" removes the ignoreTaggedTemplateExpressions option, treating it as always true.

In the next breaking change, 3.0, we can remove this option altogether ☺️

Let me know if you want to approach this in another way, this is my first PR here, happy to learn!
