chore(code-placeholders): Support path-like patterns:

- Assigns the match expression to a data attribute (data-id) to use in eleement selection. Previously, it assigned the regex expression to input.id and used the ID to select the element when updating the placeholder value. A regex that starts with a slash causes an error; input#/path/to/match isn't a valid id.
- Supports placeholders like '\/path\/to\/file.parquet'
- Refactors code-placeholders to the component pattern.
