Track Changes in @jit in Numba Version0.59.0.

[HumphreyYang]

From #294

@jstac:

Switch over to a simple @jit once 0.59 comes out

Keep track of changes in the deprecation of fall-back behaviour.

I haven't seen the notices but our lectures are still using njit in
many cases, and probably jit(nopython=True) in a few cases.

See e.g., https://python-programming.quantecon.org/numba.html

[jstac]

These substitutions should be straightforward but touch many lectures -- and hence need to be coordinated with @mmcky

@HumphreyYang we have now updated all backends to use numba>=0.59 so I will add this to my list. Are there any examples that you know of that need updating?

[HumphreyYang]

Many thanks @mmcky. The examples in my mind are cases involving @jit(nopython=True). I think we can simply change it to @jit. Here is an example where it is used: https://python.quantecon.org/mccall_model.html#implementation

thanks @HumphreyYang I have opened a PR to review starting with lecture-python.myst
