[MAP] - Performance improvement

[bsoufflet]

When zooming at the entrance marker level on area with a lot of entrances (200+ markers) we could improve the performance by :

• making the markers lighter (simple circle instead of image icon marker) ?
• not attaching an already rendered popup and a tooltip to each marker and instead create the popup when we click the marker
• OR do not attach the popup to each marker if there is too much markers and instead add in the tooltip that the user need to oom more to activate the popups
• upgrade to the latest react-leaflet 4.0.0 + leaflet 1.8 versions
• upgrade MUI to v5 (planed here [MATERIAL UI] Migrate to v5 #289) -> Bad material-ui Box performance mui/material-ui#21657 (comment)

@see #360
