[Feature] Improve yml readability

**Describe the feature**
Structure the yml so that it matches the dbt Cloud UI.

Currently, the generated yml files are sorted alphabetically, so it took me a while to decypher what part of the yaml was responsible for what part of dbt Cloud job configuration. If you structure the yml in a way that it matches the dbt Cloud UI, it is easier to understand.

Example of re-ordered yaml:

```yaml
jobs:
build:
account_id: 1
project_id: 2
environment_id: 3
linked_id: 4

# Job Settings
job_type: scheduled
name: prod - scheduled build
description: Scheduled build job on prod

# Execution settings
run_generate_sources: false
execute_steps:
- dbt build
generate_docs: true

# Triggers
triggers:
github_webhook: false
git_provider_webhook: false
schedule: true
on_merge: false

schedule:
cron: "0 4,9,13 * * 0,1,2,3,4,5,6"

triggers_on_draft_pr: false
job_completion_trigger_condition:

# Advanced settings
custom_environment_variables: []
settings:
threads: 4
target_name: "prod"
execution:
timeout_seconds: 0

dbt_version: # Inherited from environment

deferring_job_definition_id: # we defer to this environment instead
deferring_environment_id: 3
run_compare_changes: false
compare_changes_flags: --select state:modified
```

**Who will this benefit?**
Anyone that wants to match the yaml to the outcome (job configuration) in dbt Cloud.
