Find lines to highlight in examples API docs using AST #1357
Description
Is your feature request related to a problem?
The lines of examples that reference the documented API element are highlighted in the generated API docs. However, this is currently done by a simple text search, so we might also highlight some wrong lines or miss lines that still belong to a call if it's spread over multiple lines.
Desired solution
Use the AST instead to find references, and the CST to find the relevant region to highlight.
