refactor: remove unneeded double quotes

[injust]

https://github.com/dandavison/delta/blob/f5b37173fe88a62e37208a9587a0ab4fec0ef107/manual/src/configuration.md?plain=1#L36:

Note that delta style argument values in ~/.gitconfig should be in double quotes, like --minus-style="syntax #340001". For theme names and other values, do not use quotes as they will be passed on to delta, like theme = Monokai Extended.

https://github.com/dandavison/delta/blob/f5b37173fe88a62e37208a9587a0ab4fec0ef107/themes.gitconfig follows this, e.g. syntax-theme = Vibrant Sunburst and syntax-theme = Monokai Extended.

Does this actually resolve any problems, like #7?

[injust]

No, just a nitpick. I couldn't figure out how to fix #7.

Could you rebase this please?

[injust]

Rebased and built.

[uncenter]

A bunch of other keys could have their quotation "corrected", see https://github.com/dandavison/delta/blob/f5b37173fe88a62e37208a9587a0ab4fec0ef107/themes.gitconfig#L49-L53. In those lines they are only quoting the hex codes by the looks of it.

It also looks like lines like hunk-header-style entirely lack quotation marks. It looks like only hex codes and format strings have quotations.

[injust]

Think I got everything.

Built and did a basic git diff test (delta output looks identical).

Thank you!
