Tutorial: student records

[RichardSmedley]

Temporarily up on docs-staging - https://docs-staging.couchbase.com/java-sdk/current/hello-world/student-record-developer-tutorial.html

A condensed version of the Student Records tutorial found in the Server & Capella docs:

• https://docs.couchbase.com/server/current/tutorials/couchbase-tutorial-student-records.html
• https://docs.couchbase.com/cloud/tutorials/couchbase-tutorial-student-records.html

... ready to go into the SDK docs - Java initially,
then porting to the others as time allows.

Note - the build failures are bit rot in our test infrastructure 😿
but not related to any of the code samples in the PR. 🙄

I haven't run the examples, but they look like they should compile and run.

Yes, have run them all - all okay.
