Hackernews search in EVADB

[kaushikravichandran]

This PR supports searching Hackernews stories in EVADB:

• We treat Hackernews as a data source
• Algolia search API for hackernews is used for searching
• Get requests are used
• We support searching within: story, comment, URL, story, poll or a combination of them
• Syntax:

params = {
        "query": "EVADB",
        "tags": "(story,poll)",
    }
query = f"""CREATE DATABASE hackernews_data
    WITH ENGINE = "hackernews",
    PARAMETERS = {params};"""

Thanks for adding Hackernews as data source? Could you also add a documentation page for it?

Added the docs. The docs test fail now: because I have added a link to the column info of the hackernews search results table: which is in this PR, and the link will become active once the PR is merged.
