[MWPW-162043] Bolded last link in Media block

[overmyheadandbody]

Using an actual heading in the Media block leads to different text treatment as opposed to using a paragraph as a heading. Depending on this, the simple link on the last line of the text section can have either a bold or a regular font weight.

The aim of this PR is to ensure that all such regular links are bolded by default. This treatment may be required in other areas as well, but it was decided to handle just this use-case for the moment.
