Ocaml version selector on documentation page looks different and a little ugly on firefox

[nibble0101]

Issue description

When you navigate to ocaml.org documentation page, there is a select dropdown element for selecting ocaml version. The styling looks elegant when viewed on chrome or opera but it looks a little ugly on firefox, in my opinion (I am using firefox 87.0 ). I haven't tested using other browsers. Check the screenshots bellow.

Chrome

Opera

Firefox

You will notice how it looks when using firefox. It is harmless even if it is not fixed but I think it would be better to have it styled to look the same/similar to that in other browsers. Below is the default browser styling for select element in Firefox.

@patricoferris and @avsm . Let me know what you think about this. I think it will be an interesting issue to investigate for #1245

A unified drop-down styling might be quite nice, thanks @nibble0101!

Not sure if anyone is working on this.. but I wanted to drop in what the version selector looks like in Safari. Seems to be the most elegant look ;). I think a dropdown menu can be created with Bootstrap CSS.

I don't know if this is a "good first issue" or a 'medium' issue (I'm looking for another one to do).

Safari
