chore: shallow checkout on fetcing git repos

[aronwk-aaron]

for reducing size on disk cmake configuration time

[EmosewaMC]

How much is the reduction in size?

[aronwk-aaron]

none.... good catch, but it does make the cmake configuration significantly faster Looking into what the space is being used by, it's the git object pack for the json-src. and that's not something we can fix. They would need to repack the repo as suggested by our lord and savior Linus Torvalds.

This does take cmake .. from about 16s to 2s (I just switched branches and deleted the build/_deps folder a few times to get these numbers)

take a look at these stats i tracked and logs from cmake with shallow real 1m33.516s user 0m3.766s sys 0m5.188s

real 1m14.400s user 0m3.297s sys 0m4.250s

real 3m0.019s user 0m3.516s sys 0m5.047s

without shallow real 0m21.816s user 0m8.438s sys 0m5.234s

given the need for json isn't viable due to the httplib not being viable for an API, just going to opt to remove json and maybe httplib too in a different PR
