Layout/UI improvements

[WillemSleegers]

A few things I noticed that we may or may not want to look at to improve:

• [x] Add more white space at the bottom of each page
• [x] Remove 'About' from 'About/FAQ' in the navigation bar
• [x] Just have 'FAQ' as the main title of the FAQ page
• [x] The FAQ orange color is quite bright; probably better to make it lighter
• [x] Lower the orange on the Contact cards
• [ ] it's hard to see on which page/tab you are. was clearer in previous version
• [x] the mouse-over-color-change of the "Browse" button is hard to see, too subtle
• [x] in the FAQ, the difference between text and the next header is very small. I'd like a bigger contrast between the FAQ accordion headers and the inside text
• [x] the "contact" page is very plain now the panel is gone

Let's switch to Bootstrap 5.

I created a new branch to replace the FAQ; please take a look to see whether you like it!

I think I fixed all the issues for now, so I'm closing this.

Nice! One more minor thing:

• [x] max-width of text & table on home page should be smaller

[WillemSleegers]

I addressed most of these issues, except for the navbar one. I think it's fine like this actually.

yep, let's keep it like this
