Fix Bootstrap resources

[MikeAlhayek]

This is not a complete fix but just a concept test. Related to #17686

This should prevent bootstrap from being loaded twice. But, now Bootstrap is no longer available on window. Some scripts like bootstrap-select will not work because it access bootstrap using window.bootstrap.

For this to work, we would have to also convert bootstrap-select to use bootstrap via import. Alternatively, we can add window.bootstrap = bootstrap; to the TheAdmin.ts to make bootstrap available globally to prevent breaking people.

@gvkries can you at least see if this loads the bootstrap twice or is it only once?

Yeah, the window.bootstrap was a temporary patch up untill we refactored everything to work as ES6 scripts. Because we use Bootstrap everywhere as inline scripts in .cshtml pages. Did not have enough time to refactor everything.

And to be honest for the size of these files related with importing Bootstrap on everyone of them. I think it is neglectable for now. We can optimize by using the Bloom javascript framework folder over time.

I'd say merge it if it fixes the issue for now.

[MikeAlhayek]

It does not work until we convert every script that needs access to window.bootstrap to ES and import bootstrap with in. One know script is bootstrap-select.

This seems to solve the issue, bootstrap is loaded only once. But even though it fixes the issue, I think separating this specific method is more appropriate solution, because including bootstrap in autocomplete.js is unnecessary bloating the file.
