fix: skip nodes with errors

## Details

Some treesitter errors within nodes are harmless, while others can cause
constant errors to be surfaced to the user. Rather than handling errors
in different ways, skip all nodes that contain errors. We check for
errors at the query level, you can think of this like a single instance
of a component like a code block. If we checked at the top level then
any error anywhere in the tree would result in nothing being rendered.

This should resolve instances of `E976: Using a Blob as a String` as
mentioned here: #451

Can reproduce by using the null-byte: `printf '\x00\n' > temp.md`
