build(types): fix a few type errors (#7834)

This commit improves type safety in two leaf-node modules by removing `@ts-expect-error` and implicit `any` types.

In `src/lib/string.ts`, the `capitalize` function was updated to use explicit `string` types for its parameters, eliminating the implicit `any` types.

In `src/lib/geo-location.ts`, the `@ts-expect-error` in the `getGeoLocationFromAPI` function was removed by adding a type assertion to the `res.json()` call, ensuring the `geo` property is correctly typed.
