Clean up semicolons after interface blocks

[Leo5878]

This pull request removes unnecessary semicolons after interface declarations across the codebase.

Semicolons after interface blocks are syntactically allowed in TypeScript but not required. They are often considered noise and are discouraged by popular style guides (e.g., TypeScript Handbook, Airbnb). This change improves stylistic consistency without affecting functionality.

Thanks again, @Leo5878!

My thinking was that even if sqlx-ts generates types in a specific style, consumers would likely apply their own Prettier or ESLint configurations to format the generated code anyway. That said, it's still a good idea for the default output to follow standard formatting conventions as a baseline.

This is now released as v0.23.0 https://github.com/JasonShin/sqlx-ts/releases/tag/v0.23.0
