[BUG] Unable to render TOC in org-mode files

[pace577]

Describe the bug
When I try to generate the table of contents for a post with the ShowToc: true option, I don't see the TOC on the post as expected.

• Device/Os: Manjaro
• Type: Desktop
• Browser and version: Mozilla Firefox 108.0.1
• Hugo Version [ >=0.83.0 expected]: 0.108.0
• Theme Version [e.g. v4.0, master, or commit-id ]: d3d90be

Steps to reproduce the behavior:

1. Create an org file with hugo new post.org with at least one heading (Eg: * Heading )
2. Add ShowToc: true in the front matter of post.
3. Serve the site with hugo serve -D.
4. Open the page and see that the TOC is not visible.

However, note that the TOC is displayed if a .md file was made instead of a .org file.

Expected behavior:
Table of Contents was supposed to appear as expected.

Additional context
Upon debugging, I found that changing the regexp in this line from <h[1-6].*?>(.|\n])+?</h[1-6]> to <h[1-6].*?>(.|\n)+?</h[1-6]> (removed a ] character in the middle) seems to give expected behaviour.

Making this change locally fixed the bug for me, but I do not understand why it happened!

I haven't tested this on org files. Using markdown is recommended with PaperMod

Hello, just replying here to bump this issue. As @pace577 already pointed out, there is some weird closed bracket ] in the RE for some reason, and getting rid of it fixes the toc partial for both org and MD. I'm wondering why this single character change hasn't been implemented in the toc partial.
