### What?

Fixes a bug that inserted unexpected spaces before and after link text
when converting Lexical links to HTML. The extra spaces came from
indentation in the template literal used to build the anchor markup.

### Why?

The whitespace was largely unnoticed in space-delimited languages like
English but produced visible, incorrect gaps in languages without
inter-word spacing such as Japanese.

### How?

Remove the line breaks and indentations from the link-to-HTML conversion
so the anchor markup is constructed without surrounding spaces.
