Allow autocomplete for stimulus controllers when using data-controller="" or {{ stimulus_controller("") }}

[florentdestremau]

<table data-controller="fonctionnalite" class="sticky-header sticky-first-column bg-white">

Where when entering "fonctionnalite" I wish I could have the list of all my controllers in assets/controllers/* or assets/js/controllers/*. Or any js class extending the stimulus controller really.

Same goes with the symfony ux syntax with {{ stimulus_controller('fonctionnalite') }}
