This is a follow-up to cbe1671104
I changed `apt-get` arguments for x86_64 glibc builds,
but forgot to change it for x86_64 musl, aarch64 glibc and aarch64 musl.
Because of this, `upload-wheels` task failed with a message:
```
The virtual environment was not created successfully because ensurepip is not
available. On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.
apt install python3.11-venv
You may need to use sudo with that command. After installing the python3-venv
package, recreate your virtual environment.
```
This commit solves the "error: externally-managed-environment"
which started appearing since Debian 12 release.
`debian` is used as an Docker image to run devpi.

this known date we check if the system clock is wrong (if earlier than known date) and if the used
Delta Chat version may be outdated (1 year passed since known date). while this does not catch all
situations, it catches quite some errors with comparable few effort.

get_provider_update_timestamp() for exactly that purpose - it is checked manually by some dev and
updated from time to time, usually before a release.

instead of last run. while that seem to be more on-purpose, we cannot even do an “empty” database
update to update the known date.

remove that function and replace it by get_last_release_timestamp that is then updated by
./scripts/set_core_version.py - the result of that is reviewed manually anyway, so that seems to be
a good place (i prefer manual review here and mistrust further automation as also dev or ci clocks
may be wrong :)
`install_python_bindings.py` was not used by CI
and scripts, except for `scripts/run-python-test.sh`
which only used it to invoke `cargo`.
Instead of using an additional script,
run cargo directly.
The documentation is updated to remove
references to `install_python_bindings.py`.
The section "Installing bindings from source"
was in fact incorrect as it suggested
running `tox --devenv` first and only then
compiling the library with `install_python_bindings.py`.
Now it explicitly says to run cargo first
and then install the package without using `tox`.
`tox` is still used for running the tests
and setting up development environment.
cargo-zigbuild is replaced with a simple zig-cc wrapper.
cargo-zigbuild still tries to use i386-linux-musl triple,
while in zig 0.11 x86-linux-musl should be used [1].
This also gives us more control over compilation flags used
and prevents changes due to cargo-zigbuild upgrades,
as its version was not pinned.
