Support R v4.2.3 for openssl compatibility

[schlichtanders]

The new version 0.17.6 depends on R>4.3, which is a problem with openssl support.

using CondaPkg and searching for r-juliacall we get the following r-base >=4.3,<4.4.0a0 restriction

julia> CondaPkg.withenv() do
           run(`micromamba search -c conda-forge r-juliacall`)
       end

This is unfortunate, as Julia itself is bound to openssl >=3,<3.1 because of OpenSSL_jll sticking to the long term support version of openssl.

This results in 0.17.5 being used in CondaPkg (if PythonCall is also installed which adds the openssl restriction). However 0.17.5 breaks on julia 1.11.
When explicitly demanding 0.17.6, the following conda error is thrown

It seems like r-base v4.2.3 is the most recent r version which works with openssl long term support version.

[Non-Contradiction]

I'm not sure why this problem happens. JuliaCall itself only requires R>=3.4.0 in the DESCRIPTION file.
And I'm using R 4.2.1 on my main laptop, so it also should be fine with R 4.2.3.

[schlichtanders]

maybe some automatic version fixation from the conda-forge build using the feedstock?
