feat(face-detection): allowSyntheticDefaultImports for typescript

[bobbor]

When using face_detection, the final rollup output generates an esm build with imports @mediapipe/face_detection the following way:

import{FaceDetection as e}from"@mediapipe/face_detection"

this breaks when using it with NEXT.js and Typescript 5.

with the following message:

The export FaceDetection was not found in module [project]/node_modules/@mediapipe/face_detection/face_detection.js [ssr] (ecmascript).
The module has no exports at all.

the suggested change adjusts the generated import statement (and usage of FaceDetection class)

import e from"@mediapipe/face_detection"
