feat: add indentDepth prop to TOCInline component

[tomelliot]

The new features in v1 blog post for the tailwind-nextjs-starter-blog repo says

By default, all headings that are of depth 3 or smaller are indented. This can be configured by changing the indentDepth property.

But this property and feature doesn't exist in the package.

I couldn't run any tests or anything to check if this worked (none available in the repo), but I think this works 🤞

Sorry for the confusion, indentDepth was removed in the following commit 61fa6f0 since I decided to add support for nested table of content so the nested headers are automatically indented. I no longer see a need for indentDepth but you can let me know if you think otherwise?

The modifications also appears to cause it to be double indented as the nested indents are already indented in this line: https://github.com/timlrx/pliny/blob/main/packages/pliny/src/ui/TOCInline.tsx#L108

Hmm - I might be missing something, but from what I'm seeing, that works differently from what I'm hoping:

• It only applies for TOCs with asDisclosure=true
• It only applies one ml-6 at the top level. It doesn't apply additional ml-6 for each heading sublevel

What I'm hoping for:

H1
H1
  H2
  H2
    H3
    H3
H1
  H2
H1

The modifications also appears to cause it to be double indented as the nested indents are already indented in this line: https://github.com/timlrx/pliny/blob/main/packages/pliny/src/ui/TOCInline.tsx#L108

This only indents the whole TOC (for disclosure/collapsible TOC), not each individual heading sublevel

@timlrx if you're interested in including this functionality but need something else in the PR just let me know, otherwise feel free to close it if it's not relevant.

Ok thanks for the clarification. I agree that it would be nice to support indentation at various sub-heading level. I am on a break for the next two weeks so will review later.

Hey @timlrx - just a reminder in case you're interested in merging this.
