Add a quick access menu, rearrange sections and subsections

[LHBruneton-C2C]

Description of the proposal

This proposal aims at adding a quick access menu at the top of record pages. To limit the number of sections, current sections would be rearranged with subsections.

The final outcome will be:

• top of the page

• on scroll

• normal size

• normal size with long section names

• normal size with section names too long

• reduced size

For the sections, two new sections would be added:

• Resources and links - this will group all online resources
  • Downloads
  • API

• Associated content - this will group all internal links
  • Source datasets
  • Associated reuse
  • Associated service

Resulting complete dataset Layout

Motivation

Many features are being added, like feature catalog, service capabilities... see other proposals.

This results in the page getting even longer and harder to scroll.

The quick access menu allows the user to navigate easily between sections in the page.

This should fix #940

Scope

This proposal affects the dataset page.

The HTML section heading elements will also be reworked to improve accessibility.

The new display of cards lists is not part of this proposal (see #1138).
