Hi

Describe the Bug

As per Do you use the right character for replaceable text placeholders?, we should update the placeholders in the ADR template to use {{ PLACEHOLDER }}

To Reproduce

Steps to reproduce the behavior:

1. Go to https://github.com/SSWConsulting/SSW.CleanArchitecture/blob/main/docs/adr/template.md?plain=1
2. Observe the placeholders use [ placeholders ]

Expected Behavior

Placeholders should be in the format {{ PLACEHOLDER }}

Tasks

• Update placeholders

Thanks!

@danielmackay, are you happy that I look at replacing these placeholders?
