Merge pull request atomvm#1102 from UncleGrumpy/doc_fix_internals

Fix documentation typo that casues functions to not be rendered

Remove a stray block indent that prevented two function in the same
"````{only} html" block to be left out of the rendered documentation.

When multiple :::{doxygen} directives are given in the same
"````{only} html" block they need to be separated by an empty newline.

These changes are made under both the "Apache 2.0" and the "GNU Lesser General
Public License 2.1 or later" license terms (dual license).
