Update `deprecated` to use the attribute template

[ehuss]

New rules:

• ❗ attributes.diagnostics.deprecated.duplicates
• ❗ attributes.diagnostics.deprecated.behavior
• ❗ attributes.diagnostics.deprecated.generic-message
• ❗ attributes.diagnostics.deprecated.message
• ❗ attributes.diagnostics.deprecated.fields
• ❗ attributes.diagnostics.deprecated.containers

Renamed rules:

• attributes.diagnostic.deprecated.allowed-positions is now attributes.diagnostics.deprecated.allowed-positions (fixed typo)
