Upgrade Jinja2 dependency version specification to address CVE-2024-2…

…2195

CVE-2024-22195 identified an issue in Jinja2 versions <= 3.1.2. As such
we've gone and changed are dependency requirement specification to be
3.1.2 or greater (but less than 4).

Note: Preivously we were using the `~=` version specifier. However due
to some issues with the `~=` we've moved to using `>=` in combination
with `<`. This gives us the same range that `~=` gave us, but avoids
a pip resolution issue when multipe packages in an environment use `~=`
for the same dependency.
