standardize yml indentation under the 'models:' line on the README

[leoebfolsom]

This is a:

• documentation update
• bug fix with no breaking changes
• new functionality
• a breaking change

All pull requests from community contributors should target the main branch (default).

Description & motivation

The yml indentation in the README is inconsistent. As someone who is not a yml expert but tries to stay consistent, wants my team to be consistent, and aspires to mostly get my yml indentation right on the first go, it is confusing to see inconsistency in the README.

Checklist

• I have verified that these changes work locally on the following warehouses (Note: it's okay if you do not have access to all warehouses, this helps us understand what has been covered)
  • BigQuery
  • Postgres
  • Redshift
  • Snowflake
• I followed guidelines to ensure that my changes will work on "non-core" adapters by:
  • dispatching any new macro(s) so non-core adapters can also use them (e.g. the star() source)
  • using the limit_zero() macro in place of the literal string: limit 0
  • using dbt_utils.type_* macros instead of explicit datatypes (e.g. dbt_utils.type_timestamp() instead of TIMESTAMP
• I have updated the README.md (if applicable)
• I have added tests & descriptions to my models (and macros if applicable)
• I have added an entry to CHANGELOG.md

Question for the team: seeing as this is only an update to the README, do I need to:

• Update the CHANGELOG?
• Create an issue?
• Do anything else?

Thank you!

Thank you for fixing this indentation, @leoebfolsom ! 🙌

No need to open an issue or update the CHANGELOG.

Thanks again for getting this buttoned up.
