The changes in this pull request modify the wiki link patterns to skip escaped wiki links. Consistent with Obsidian, wiki links can be escaped with a single backslash \ character before the first opening bracket, e.g., \[[escaped]]. If the opening bracket is preceded by two backslashes, it is not escaped, e.g., \\[[not escaped]].

This pull request resolves the following issue:

Note For now, there is no way to escape obsidian wiki links. Every link will be replaced with a hugo link.

The following regex is added to the wiki link regex: (?:^|(?<=[^\\])|(?<=\\\\))\[\[(.*?)\]\].

• \[\[(.*?)\]\]: Wiki link pattern, two opening square brackets, followed by an arbitrary character sequence, end ended by the next two closing square brackets.
• (?:^|(?<=[^\\])|(?<=\\\\)): Specifies that to be a valid wiki link, the first opening bracket must be preceded by:
  1. the start of the sequence ^,
  2. any character that is not backslash, or
  3. two backslashes.
