Fix modal with Bootstrap 5

[Haititi]

The <div class="fm-modal"> you are injecting is missing the bootstrap 5 class modal, so it should become:
<div class="modal fm-modal">.

Can you please merge this pull request? your file-manager is not usable as it is for the moment.
Please also update https://github.com/alexusmai/laravel-file-manager !
Thanks a lot!

@alexusmai can you please merge this PR to fix your modals?
None of your modals are usable without this fix.
Thanks in advance.

Please merge this! For me the modals are completely broken without the modal tag.

Just tested, the modal is not visible when opened. You should add !important tags to the display:block and position:absolute css selectors like I did in my fork: https://github.com/siebsie23/vue-laravel-file-manager/blob/master/src/components/modals/ModalBlock.vue

I don’t understand why add this class, it will be overwritten by the existing one.
And modal windows are displayed normally..

[siebsie23]

For me it doesn't load the CSS variables because they are loaded with the .modal selector.

@alexusmai Can I open a new PR that also adds the !important tags I mentioned which fixes my and @Haititi 's issue?
