### Steps to reproduce

1. Look at a link in a PageHeader description or a form description


### What is the buggy behavior?

From an accessibility perspective, the links are not distinguishable enough from the surrounding text.

### What is the expected behavior?

Links should be clearly distinguishable. Possibilities include:

* Begin of the insertionWhenever there is a link in a description ofEnd of the insertion Begin of the deletion IncreasingEnd of the deletion the Begin of the insertionPageHeader, theEnd of the insertion Begin of the deletion color contrast to at least 3:1 (contrast betweenEnd of the deletion link Begin of the insertionshould have anEnd of the insertion Begin of the deletion text and surrounding text; **not** between text and background)

* Adding link styling (e.g.End of the deletion underline Begin of the insertioneffect. We are therefore following Primer's [guidelines for links in text](https://primer.style/product/components/link/accessibility/#guidelines).End of the insertion Begin of the deletion links)End of the deletion


### Notes

Some automated checks for the problem have been silenced to make automated tests pass. These should be re-enabled.

I.e. when `expect(page).to be_axe_clean` is used, make sure this test is not disabled via `skipping("link-in-text-block")`.

### Screenshots and other files

Two occurences of the violation in the new SCIM Clients UI (the bottom of the two is even hard to distinguish for me):
