Merged PR 4687: Bugfix - Removal of SH fields that no longer exist

# Description

After the sync this morning in Core in Airbyte, we have some issues in SH User. This attempts to remove no longer existing fields, namely:
- id_airbnb
- airbnb_url
- platform_comms_recipient

# Checklist

- [X] The edited models and dependants run properly with production data.
- [X] The edited models are sufficiently documented.
- [X] The edited models contain PK tests, and I've ran and passed them.
- [ ] I have checked for DRY opportunities with other models and docs.
- [ ] I've picked the right materialization for the affected models.

# Other

- [ ] Check if a full-refresh is required after this PR is merged.
