[v1.2] Fix bootstrapping (#34477)

* Fix bootstrap if repository path contains symlinks. (#32945)

Pigweed seems to fail with:

    ERROR at /home/angus/projects/connectedhomeip/third_party/pigweed/repo/pw_build/facade.gni:187:7: Assertion failed.
    assert(_dep_is_in_link_dependencies,

when the repo path has symlinks in it and bootstrap is run.

The workaround is to change to the symlink-resolved path temporarily while doing
the pigweed parts of bootstrap.sh.

Fixes #31851

* Bump python versions to fix bootstrapping
