Fix StackBlitz Popovers and Tooltips examples

[julien-deramond]

Step 2 of #36391

This PR contains

• New stackblitz option for the example shortcode
• Rename js_snippet to stackblitz_add_js option for the example shortcode in order to identify easily what's related to StackBlitz
• Rewrite the example shortcode's documentation and reorder the options
• Hide the StackBlitz edit button of the first Popover example and use data-bs-title instead of title for the other Popover examples as discussed in Allow popovers examples to be tried on StackBlitz #36127 (comment)
• ⚠️ Use data-bs-title instead of title for the Tooltip and Popover examples

Live previews

Popovers

• Live Demo.
• Custom popovers: popover's title is now displayed in StackBlitz but without the custom style (will be handled in another PR in step 3).
• Dismiss on next click

Tooltips

• Tooltips on links
• Custom tooltips: displayed in StackBlitz but without the custom style (will be handled in another PR in step 3).

Following a discussion with @GeoSot a4153f4 contains the following modifications:

• Removing of stackblitz param for the example shortcode only used in one example to simplify the use of this shortcode
• It implies that all popovers and tooltips examples in the doc use data-bs-title instead of title
• A reusable warning callout is in place (wording should be improved; if you have a better way to explain it don't hesitate :) )
