Explicitly install python tool dependencies (#195)

## Usage and product changes

Since the upgrade to rules-python v0.24
(typedb/typedb-dependencies#460), we are required to
explicitly install python dependencies in the WORKSPACE file. The python
tools happened to be unused, so these errors were not visible until the
sync dependencies tool was restored.
