[Bug] Build fails if .swcrc includes comments #22
Description
Describe the bug
.swcrc files support comments, but this addon reads it as basic JSON, resulting in a failure:
=> Failed to build the preview
SyntaxError: Expected double-quoted property name in JSON at position 399 (line 19 column 5)
Steps to reproduce the behavior
Add a comment to the project's .swcrc and build the docs.
Expected behavior
It should not fail when there are comments in .swcrc.
