Update Inspiral.yaml

[nilsvu]

Proposed changes

Small updates to the BBH Inspiral.yaml:

• Switches time stepper to AdamsMoulton because it's faster.
• Trigger AH observations more often, but not constraint energy
• Observe fewer volume fields to save disk space

Upgrade instructions

Code review checklist

• The code is documented and the documentation renders correctly. Run
  make doc to generate the documentation locally into BUILD_DIR/docs/html.
  Then open index.html.
• The code follows the stylistic and code quality guidelines listed in the
  code review guide.
• The PR lists upgrade instructions and is labeled bugfix or
  new feature if appropriate.

Please add that this is an issue with the AH finders not sharing initial guesses and that it needs to be fixed.
