Update pandas version in requirements.txt

[gasrios]

I could not build Urutu Rent a Home on Ubuntu 20.04, because Pandas 1.1.0 uses Python 3.7 functions that were deprecated in 3.9. The patch below fixed this by upgrading Pandas to 1.3.4, please consider applying it:

git apply /dev/stdin <<'END'
diff --git a/requirements.txt b/requirements.txt
index af79dd1..d85951b 100644
