Actually, I was even dumber than that. I installed Bootstrap 4.6.0 in my project, but I copied text from the docs for Bootstrap 5.
So I didn't really need to change those selectors, I just needed to copy the right text from the Bootstrap docs.
I'll bet you got tricked into using Bootstrap 5 instead of Bootstrap 4 like I did. That means your selectors need to change from:
    $('[data-toggle="tooltip"]').tooltip()
    $('[data-toggle="popover"]').popover()
to
    $('[data-bs-toggle="tooltip"]').tooltip()
    $('[data-bs-toggle="popover"]').popover()
