This PR add a caution alert at the beginning of Installation section for all bundle requiring StimulusBundle

[smnandre]

Imho, the "caution" may be a bit too strong (red block)... maybe a "info" should do the job ?

I made a quick check (i was not sure) so, for information, those packages require symfony/stimulus-bundle in their composer file, so the risk of installing them without Stimulus bundle is null

• Chartjs
• Notify
• React
• Svelte
• Turbo
• Vue

(not saying that does not deserve a message in the doc)

And those ones do not

• Autocomplete
• CropperJS
• Dropzone
• LazyImage
• LiveComponent
• Swup
• TogglePassword
• Translator
• Typed

Finally (to cover all the packages), TwigComponent does not depend / use / require StimulusBundle.

This can definitely be a gotcha. We could require stimulus-bundle in the rest of the packages. It is not technically required, but it is practically required.

Thanks Romain!
