[repo] Sync-up .editorconfig with main repo

[CodeBlanch]

Changes

• Updates .editorconfig for recent changes done in the main repo. Enables some things as suggestions. Quiets some spammy stuff which was previously enabled but generally ignored (use primary constructor suggestion, folder structure should match namespace suggestion). Deals with warnings that came with .NET 9 SDK in main repo and will likely pop up here

Merge requirement checklist

• CONTRIBUTING guidelines followed (license requirements, nullable enabled, static analysis, etc.)

@CodeBlanch, I think that changes in this files should trigger build for all files (modification of detect-changes step is needed).

EDIT: nvm. lint is executed.
