Fix func_persist: do not use inspect.formatargspec (gone as of Python
3.11)

calculate 1+1"

<!-- Describe your changes here in detail -->

The method `inspect.formatargspec` has been deprecated since Python 3.5,
now removed as of 3.11. `func_persist` still uses it, so we replace it
with `inspect.signature`.

Another option would be to replace it with
`sageinspect.sage_formatargspec`. I think that func_persist should only
be used with Python functions, not Cython, and `inspect.signature` is
nicer for Python functions. If the function is defined as `def test(n:
int) -> int:`, For example, then `inspect.signature` will return `(n:
int) -> int` while `sageinspect.sage_formatargspec` will just return
`(n)`.

This should fix sagemath#36302.
