It usually helps to specify why you need to change something. In this particular case: why is it necessary to update the version of the action?

[mosfet80]

The libraries currently used allow the use of Python v 3.5 (eol 2020), which is not safe to use.

meson build to 1.0.3 update to setup-python@v4 meson-version to 1.2.2

now minimum requirements are:

[Python] version 3.7 or newer [Ninja] version 1.8.2 or newer
