### Rationale for this change With the changes in #40455 reticulate can't find pyarrow. ### What changes are included in this PR? Set `RETICULATE_PYTHON_ENV` to `ARROW_PYTHON_VENV`. See https://rstudio.github.io/reticulate/articles/versions.html#order-of-discovery why we can use `RETICULATE_PYTHON_ENV`. This also simplifies the current configurations: * Install Meson by `apt-get`. * Use `ARROW_PYTHON_VENV` to install Sphinx and related packages. ### Are these changes tested? Via archery. ### Are there any user-facing changes? No * GitHub Issue: #40535 Lead-authored-by: Raúl Cumplido <raulcumplido@gmail.com> Co-authored-by: Sutou Kouhei <kou@clear-code.com> Signed-off-by: Sutou Kouhei <kou@clear-code.com>
