Tests with invalid HTML void end tags

[zcorpan]

I noticed that some rendering test was using <source ...></source> HTML syntax, which is invalid HTML because source is a void element (but doesn't make the test expectations invalid). However, there are also some tests that use </br> end tags, which are parsed like <br> start tags, which might very well not be intentional and make the test expectations invalid, though I haven't investigated them in detail.

We could clean this up and lint it, similar to />:

• Fix invalid HTML: /> syntax on non-void elements #40473
• Add a lint rule for /> syntax on non-void HTML elements #40498
