Columns prefix and suffix on wrapper

[promatik]

Related with https://github.com/Laravel-Backpack/CRUD/pull/3435.

This adds ability to add prefix and suffix to each column wrapper.

Note to self: we also talked about adding a wrapper[separator] attribute. Details in https://github.com/Laravel-Backpack/CRUD/pull/3435#issuecomment-769476582

@promatik time to merge / close this. Still think it's a good idea & implementation? If so, please ask @pxpm to test & merge.

Bump! @promatik do you still think this is worth doing?

[promatik]

I think this is pretty cool 🤷‍♂️

And it can only be achieved with this feature, or, by hacking into the getFieldAttribute() { return "¿$this->field?";

Another example;

[
    ...
    'wrapper' => [
        ...
        'prefix' => '¿',
        'suffix' => '?',
    ],
    'prefix' => '—',
    'suffix' => '!',
],

Quick note, this highlights an inconsistency between the place of the column prefix and suffix, inside or outside the wrapper.

In some fields column prefix/suffix are inside, others are outside. In my opinion it should always be outside, and if the devs want the prefix/suffix inside, use the method introduced in this PR, inside wrapper 👌

But, that is a breaking change, so not for now 🤷‍♂️

@promatik if you think this is still worth doing, please add v6 docs for it (instead of v5) then ask Pedro to review and merge.

@pxpm updated docs to v6 https://github.com/Laravel-Backpack/docs/pull/389 👌
