feat(compute): adds pg_session_jwt extension to compute image

[davidgomes]

Problem

We need the pg_session_jwt extension in the compute image. This PR adds it.

Summary of changes

I added the pg_session_jwt extension in a very similar way to how the pggraphql and pgtiktoken extensions were added (since they're all written with pgrx). Then I tested this.

$ cd docker-compose/
$ PG_VERSION=16 TAG=10667533475 docker-compose up --build -d
$ psql postgresql://cloud_admin:cloud_admin@localhost:55433/postgres

cloud_admin@postgres=# create extension pg_session_jwt;

CC @devjv @conradludgate @stradig @vadim2404 Going to keep this as a Draft for now, but it works and you can all take a look.

[skyzh]

As long as the compute node image can be built successfully I'm confident that this can be merged.

[conradludgate]

Looks good, although maybe we shouldn't merge just yet. I don't think we have a way to feature gate extensions so it's best if we manually configure the compute images with this one built in CI for now
