feat: added puppeteer loader node

[AidanTilgner]

I updated the components package to add the puppeteer integration described in this issue. This is my first PR here, so let me know if I need to change anything/everything.

• Add Puppeteer Loader node
• Puppeteer Loader node should be able to scrape data from webpages
• Build successful

Note: Puppeteer is updating their default headless mode, and therefore a warning is displayed and the option to update the headless proeprty to headless: "new" is offered. However, it seems that the decision to update to headless: "new" is controlled by the PuppeteerWebBaseLoader langchain loader. I don't think this is an issue, as the new headless mode will become the default soon, but I figured I'd mention it.

It seems that there are some merge conflicts now since the new emergency changes were made. I will update this tomorrow.

How are you testing it?

[AidanTilgner]

I ran the build and start command according to the contributing guidelines. I also created the above chain for testing purposes. I confirmed that the "Puppeteer Web Scraper" node was scraping documents successfully. Then I used the "Pinecone Upsert Document" node to confirm that they were being scraped and then pulled into memory by the language model. Everything works the same as the cherio reference code.
