Replace redis driver with FalkorDB driver

Replace redis driver with FalkorDB native python driver

[logan-markewich]

Seems like the new version of falkorDB requires python3.10 -- I'll update the BUILD file for CICD so that tests pass and reflect this requirement

[logan-markewich]

Or, I guess I can't push to this PR (must be a private fork)

To fix this
a) In llama-index-integrations/graph_stores/llama-index-graph-stores-falkordb/BUILD update it to look like this:

poetry_requirements(
    name="poetry",
    interpreter_constraints=["==3.10.*"],
)

b) In llama-index-integrations/graph_stores/llama-index-graph-stores-falkordb/pyproject.toml, bump the version from 0.1.2 to 0.1.3

[gkorland]

We released a new version of the falkordb 1.0.4 client that supports python 3.8

@gkorland oh awesome! :)

[logan-markewich]

@gkorland one final ask -- can you remove the changes from legacy (it's not meant to be modified) as well as bumping the version of this graph store integration package in the pyproject.toml (version = "0.1.3")

[gkorland]

@logan pushed the changes
