Updates to MR templates and qblox/recent.md

- [ ] Tested on hardware (or N/A).

- [ ] `CHANGELOG.md` and `AUTHORS.md` have been updated (or N/A).

- [ ] Windows tests in CI pipeline pass (manually triggered by maintainers before merging).

   - _Maintainers do not hit Auto-merge, we need to actively check as manual tests do not block pipeline_

For reference, the issues workflow is described in the [contribution guidelines](https://quantify-quantify-core.readthedocs-hosted.com/en/main/contributing.html#merge-requests-workflow).

1. [ ] Review `CHANGELOG.md` and `AUTHORS.md` have been updated.

1. [ ] Update `Unreleased` chapter title in `CHANGELOG.md` to `X.Y.Z (YYYY-MM-DD)`. Commit it.

    - Also update `Unreleased` title in `docs/tutorials/qblox/recent.md` (if present).

1. [ ] Review `@deprecated` and `FutureWarning`s that can be cleaned up now.

1. CI pipeline:

# Recent interface changes

## Unreleased: Long waveform support

## 0.13.0: Long waveform support

The {code}`instruction_generated_pulses_enabled` option (see {ref}`Cluster <sec-qblox-instruction-generated-pulses>` and {ref}`Pulsar <sec-qblox-pulsar-instruction-generated>` user guides) is deprecated and will be removed in a future version. Long square pulses, staircase pulses and long ramps can be generated with the newly introduced helper functions {class}`~quantify_scheduler.operations.pulse_factories.long_square_pulse`, {class}`~quantify_scheduler.operations.pulse_factories.staircase_pulse` and {class}`~quantify_scheduler.operations.pulse_factories.long_ramp_pulse`. More complex long waveforms can now also be created from the {class}`~quantify_scheduler.operations.stitched_pulse.StitchedPulseBuilder`, which generates a {class}`~quantify_scheduler.operations.stitched_pulse.StitchedPulse`. For more information, see {ref}`Long waveform support <sec-qblox-cluster-long-waveform-support>`.
