Populate instrument session via graph

[EmsArnold]

Use graph-nightly for both instrument sessions and workflows.

Select instrument session from drop-down list provided by graph-nightly query, give free visit input which allows for any session to be set.

Graph-nightly should be up to date now with Workflows main, so repository can go back in (if you want it).

I have added repository back in, but trying to do pnpm relay with the new schema gives:

[INFO] [default] compiling...

thread 'main' panicked at crates/schema/src/in_memory.rs:836:21:

Removing

extend schema
  @link(...)

resolves the issue, but feels like it isn't correct?

[VictoriaBeilsten-Edmands]

Yes, we also remove that last part for the same reason.
