fix: hover content indentation issue

From a previous change, when creating a hover
indentations were replaced with the html entity
non breaking space.

The issue is that the indentation property
is optional and this was not considered in that
change. Due to this the markdown content would
be incorrect.

This change performs the markdown content modification
only when the expected parameters exist.
