Media WYSIWYG token matching conflicts with other token types

When running a standard D7 to D8 node migration with media_wysiwyg tokens and other contrib/custom tokens, the REGEX pattern matching conflicts, breaks the migrated content, and results in the following warning:
[warning] Message: The following media_wysiwyg token in node NODE_ID does not have valid JSON: ...

After digging into this, it seems like the media_wysiwyg_filter plugin regex is not specific enough in \Drupal\media_migration\Plugin\migrate\process\MediaWysiwygFilter::transform

An approach I've used successfully is to check for the media_wysiwyg JSON brackets within the tokens in the REGEX and adding the JSON brackets back in the decode function:

Before:

line 50: $pattern = '/\[\[(?<tag_info>.+?"type":"media".+?)\]\]/s';
line 63: $tag_info = $decoder->decode($matches['tag_info'], JsonEncoder::FORMAT);

After:

line 50: $pattern = '/\[\[\{(?<tag_info>.+?"type":"media".+?)\}\]\]/s';
line 63: $tag_info = $decoder->decode('{' . $matches['tag_info'] . '}', JsonEncoder::FORMAT);

However, this workaround will still conflict with any contrib/custom tokens using JSON, so a more thorough solution is required.
