[OV JS] Add optical-character-recognition sample notebook (openvinoto…

…olkit#25191)

### Details:
 - *added code in node notebook*
 - *updated the samples list in readme*
 
### Workarounds which still needs to be worked upon 
- couldn't find the js equivalent method for `cv2.getTextSize()` (opencv
python method) which is used for getting the height and width of the
crop text the opencv-wasm package does not have this api , in the
current implementation I have written a custom function `getTextSize`
which uses canvas to get the width and height of the text

- `text-recognition-resnet-fc` model IR was larger in size it was around
355MB hence I did not included it in my PR

Please provide Feedback  @Aliczi @vishniakov-nikolai
