update web_base.py to have verify option

[jackfrost1411]

We propose an enhancement to the web-based loader initialize method by introducing a "verify" option. This enhancement addresses the issue of SSL verification errors encountered on certain web pages. By providing users with the option to set the verify parameter to False, we offer greater flexibility and control.

Who can review?

And by adding verify option: you can finally pass in headers such as

headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36'}

to bypass the SSL verification.

headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36'}
loader = WebBaseLoader(web_path="https://SO_AND_SO.com", header_template=headers, verify=False)
data = loader.load()

This solves a lot of issues that I faced in the recent past.

The older version of web_base.py gives errors:

The newer version of web_base.py is working just fine:
