added macos dependency installation

[rrmanukyan]

Added missing dependency installation on generic MacOS runner

High Level Overview of Change

Installing Python and cmake before the build process

Type of Change

• Chore (no impact to binary, e.g. .gitignore, formatting, dropping support for older tooling)

Test Plan

A test pipeline was run on the forked repo

I think these can be moved to the github-runner provisioning pipeline, so it wont be run for every build

When dependencies are installed, each step takes around a second and the packages are not being reinstalled every time.

The reason it was not put in runner provisioning script is to keep it generic and the build pipeline runner agnostic.

we may need to specify the python version at least, once there is new python version, it might potentially cause some issue.
Also I remember brew install will try to upgrade versions for install packages, that might take some time.

Added Python version and moved both python and cmake installation under condition which will prevent unexpected updates.

Tests:
First run on a fresh runner: https://github.com/rrmanukyan/rippled/actions/runs/12635228168/job/35204685814
Second run: https://github.com/rrmanukyan/rippled/actions/runs/12635752221/job/35206312378
