## Key Updates in the ADR
- **Separation of Migrations in PRs**: Migrations are now required to be
carried out in separate pull requests. This change is intended to
improve the monitoring and management of database schema changes during
deployment.
- **Primary Key Requirement for New Tables**: A new paragraph mandates
the inclusion of primary keys in all new tables, emphasizing the
importance of data integrity, efficient data retrieval, and supporting
table relationships. Additionally, by adding primary keys, we resolve
the issue of migrations failing during upgrades in replicated database
setups, as we are not using PostgreSQL replica identities. Exceptions to
this rule require a compelling justification.
Also added better structuring and styling to ADR for better readability.
https://linear.app/unleash/issue/2-1680/adr-specify-tables-when-querying-columns
This PR includes my suggestion of a "Specificity in database column
references" ADR.
The ADR proposes a standard for explicitly specifying the full table
name or alias for each column in our SQL queries, especially for queries
with joins between multiple tables. This decision is a direct response
to recent ambiguity errors encountered due to a database migration,
emphasizing the need for clearer SQL query standards in complex joins
and schema changes.

## About the changes
While working on Terraform I identified some issues with how our backend
handled some requests. This happened because the Terraform client was
unaware of new fields and was not sending them. This resulted in bad
behavior as some of those missing fields were treated in the backend as
`null` and removed existing data from the DB.
This ADR aims to shed some light on the problem and specifies how our
server should handle these requests.

This PR puts our contributing guidelines in the sidebar of the unleash
documentation. Currently there was no way of navigating to them easily,
which made our contribution guides and ADRs less useful. This PR adds
them to the sidebar as their own category, and adds an ADR for domain
centric language.
