Update to ubuntu 24.04

See lf-lang/lingua-franca#2458

reactor-cpp does not, like reactor-c and reactor-rs, contain a reference to lingua-franca. So some of the tests are running out of lingua-franca master, thus they fail. When the lingua-franca PR is merged they should pass.

@erlingrj why is the ubuntu-latest CI now failing?

geninfo: ERROR: Unexpected negative count '-6' for /usr/include/c++/13/bits/char_traits.h:433.
	Perhaps you need to compile with '-fprofile-update=atomic
	(use "geninfo --ignore-errors negative ..." to bypass this error)

mmhh looks strange

[erlingrj]

It is due to race conditions in the coverage, it is fixed by adding '-fprofile-update=atomic in lingua-franca. But reactor-cpp checks out lingua-franca#master so it doesn't see those fixes until it is merged to master
