chore(deps): update flint to v0.5.0 and use slim super-linter (#1887)

## Summary

- Update flint from v0.4.0 to v0.5.0
- Switch from full Super-Linter image to the slim variant (~2 GB
smaller), which excludes Rust, .NET/C#, PowerShell, and ARM template
linters that this project doesn't use

## Test plan

- [x] `mise run lint` passes locally
