[Tests] update R, Python and Julia (#14866)

* update renv

* Update to R 4.6.1

* Update R packages

* Update R 4.6.1 in actions too

* update uv and python

* Update julia and deps

* update uv action in workflow

* Fix retina image-dimension smoke test after matplotlib bump

matplotlib 3.10.8 -> 3.11.1 shifted the tight-bbox crop width of the
test figure by one pixel (537 -> 538), breaking the CI assertion on
both Windows and Linux.
