PYTHON-5851 Run setup-uv-python.sh before install-dependencies.sh

PYTHON-5851

Changes in this PR

Reorder script execution in setup-dev-env.sh so that setup-uv-python.sh (which configures UV_PYTHON) runs before install-dependencies.sh (which uses uv to install dependencies). Previously the ordering caused install-dependencies.sh to run without the correct Python version set.

Test Plan

Verified via Evergreen patch on other-hosts-rhel8-arm64-latest / test-no-toolchain-sync-noauth-nossl-standalone (patch 6a2055295e7fc100078cc5c3) — task that was previously failing now passes.

Is test.asynchronous.test_cursor.TestCursor.test_maxtime_ms_message a known failure? Seems to be failing on master as well.
