ae5f72027f ci: Add workaround for Homebrew's python link error (Hennadii Stepanov)
Pull request description:
Homebrew [promoted](https://github.com/Homebrew/homebrew-core/pull/150390) `python@3.12` to the default `python3`. Now, our "macOS native" CI job is facing the following issues:
1. Installing `qt@5` [requires](https://github.com/bitcoin/bitcoin/actions/runs/8216848118/job/22471875454#step:4:51) re-installing `python@3.12`:
```
==> Fetching dependencies for qt@5: readline, python@3.12 and gettext
```
2. Re-installing `python@3.12` [fails](https://github.com/bitcoin/bitcoin/actions/runs/8216848118/job/22471875454#step:4:127) due to symbolic link conflicts on macOS `x86_64`:
```
==> Pouring python@3.12--3.12.2_1.ventura.bottle.tar.gz
Error: The `brew link` step did not complete successfully
```
3. Homebrew's `python@3.12` is marked as externally managed (according to PEP 668), necessitating different approaches for installing Python packages.
This pull request resolves all the issues mentioned above.
