feat(javascript): add function signature and props to DsComponent #81

- Added the ability to extract function signature and props from TypeScript function expressions and JS functions.
- Updated the `DsComponent` data class to include the new fields `signature` and `props`.
- Modified the `ReactPsiUtilTest` to include assertions for the extracted function signature and props.
