[tex] Adjusting the TOC style

[inkydragon]

xref: JuliaLang/julia#43698

1. Use compact line spacing in TOC: \cftbeforepartskip, \cftbeforechapterskip
2. Increase the spacing between chapter numbers and chapter names: \cftchapternumwidth
3. Increase indent before section number: \cftsectionindent

output: DocumenterLaTeX-toc#1750.pdf v.s. DocumenterLaTeX-master+7beb208b3.pdf

[inkydragon]

This pr does not modify the display depth in the TOC (\settocdepth).

And with only the chapter names (\settocdepth{chapter}):

DocumenterLaTeX-chapter-only.pdf

Any idea about the failing test? Maybe rebase?

@fredrikekre Is merging this what we broadly need for the pdf of the julia manual to look nicer, and is this the right place (as opposed to the julia repo PR linked above)?

@inkydragon Can you look into the failing test? It looks relevant.

[fredrikekre]

Looks good, I don't think the failure is related, I can look at it tomorrow.

Can you add a note in the changelog?

[ViralBShah]

Bump.

[fredrikekre]

Tests should be fixed by 33c53bd.

[ViralBShah]

@inkydragon Can you rebase to pull in the fix above to fix the failing test?

[ViralBShah]

We still have spacing issues - however I think that the PDF should only have TOC depth at chapter level (and not section level)
