Update Substrate ecosystem dependencies to polkadot-v0.9.6 series

[JoshOrndorff]

Closes #531 by updating all of our dependencies

This updates the spec version of all runtimes. No storage migration is necessary for randomness collective flip as explained here paritytech/substrate#9061 (comment)

This requires changing the spec names: see bccbcf8

This is pretty close to done. Just have to vanquish the testing beast.

Status of Rust tests:

• Some of them still don't run in CI. This has been the case since before this PR. See Add all crates to root cargo toml and fix author mapping build mock #521 All the ones that CI skips pass for em locally.
• Of the ones that do run, most of them pass.
• The only ones failing (both locally and in CI) are the integration tests for the subcommands. These tests have been notoriously flaky since the moment they were introduced. See Rust-based integration tests for PurgeChain subcommand #356 I've tested the subcommands manually and they work as expected:

# Show that base path is empty of data to begin with
joshy@pop-os:/tmp/doing-cis-job-for-it/chains/moonriver/db$ ls

# Run a node and let it start syncing
joshy@pop-os:~/ProgrammingProjects/moonbeam$ ./target/release/moonbeam --base-path /tmp/doing-cis-job-for-it --chain moonriver

# Show that some data was downloaded
joshy@pop-os:/tmp/doing-cis-job-for-it/chains/moonriver/db$ ls

# Run the purge command

# Show that the data is now empty

Status of the TS tests:
They won't run in CI until the above-mentioned rust test issues are solved.
They run locally, and all pass except for one:

  196 passing (1m)
  16 pending
  1 failing

  1) Trace filter - Concurrency
       "before all" hook: Setup: Create 50 blocks with 1 contract loop execution each for "should allow concurrent execution":
     Error: Timeout of 5000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves. (/home/joshy/ProgrammingProjects/moonbeam/tests/tests/test-trace-concurrency.ts)

I updated the spec templates (and edited the PR description to include the information)

[JoshOrndorff]

@crystalin Thank you so much for finishing this.

The expects you added to the test will make them easier to diagnose in the future.
