Feat: Add more features to the pinterest module

[priyankeshh]

Describe the feature

I am adding 2 features to the pinterest module:

Feature 1: Search Pins by Keyword
Description:
Add functionality to search for pins containing a specific keyword on Pinterest. Users will be able to provide a keyword, and the script will scrape pins related to that keyword, including details such as pin title, description, link, and image URL.

Feature 2: Get Pin Details

Description:
Implement a feature to fetch details about a specific pin on Pinterest. Users can provide the URL of a pin, and the script will extract information such as pin title, description, number of saves, and number of comments.

Note

• Please create a separate module for this, as in the folder and project structure (if it is already created, just add your features as functions in the same module).
• Do not use the `selenium web driver as it is incompatible with all devices and cloud platforms.
• Before making any changes, please check whether the module you want to add exists. If yes, then you can add your functionality as a method only make a separate module and class for it.

All the best 👨‍💻
