Previously, #4090 removed runtime support for R UDF operators due to licensing constraints. Following the design proposed in #4155, we now manage all R UDF–related code in a separate repository and have the Texera main repository consume it as an optional plugin. For prerequisites and installation instructions, please refer to the `README.md` in the plugin repository: https://github.com/kunwp1/texera-rudf. Note: This repository is currently a prototype under my personal account. Once this PR is merged, I plan to transfer it to the Texera organization. ### Any related issues, documentation, discussions? <!-- Please use this section to link other resources if not mentioned already. 1.

What changes were proposed in this PR?
Removed official support for R-UDF. The frontend is not changed, but during execution user will receive an error about unofficially supported R-UDF. We plan to move the R-UDF to a third party hosted repo, so users can install the R-UDF support as a plugin.
Any related issues, documentation, discussions?
This change was due to the fact that R-UDF runtime requires
rpy2, which is not apache-license friendly.resolves #4084
