Add Weekly Schedule to footer

[kiennguyenchi]

Solve Issue #54

I added hyperlink of Weekly Schedule to the footer in docusaurus.config.js.

I removed hyperlink of Weekly Schedule in Contents page in docs/intro.md.

Why it looks like "prettier" didn't work? I think it should be something like this >

          label: "Contents",
          to: "/",
        },
        {
          label: "Weekly Schedule",
          to: "/weeklyContents",
        },

        },

So you mean that I should replace the single quotes with double quotes? We use single quotes in the entire file, so I think we should not.

We don't have prettier in the tree yet, see #50.

@kiennguyenchi @humphd what I meant exactly is this ->

I didn't see anything bad in this PL, except this.
Overall, it looks good to me...

I have also tested this and nothing to change from above comments

Thanks - this makes sense and I'm sure will be used by many as another quick way to return to the weekly schedule.
