bug: opening links in new tab from homepage shows HTML

[engineereng]

Description:

Opening the following links from https://docs.ubclaunchpad.com/ in a different browser tab results in the viewer seeing the raw HTML:

• the link to https://docs.ubclaunchpad.com/introduction.html (under the "Get started" button)
• the link to https://docs.ubclaunchpad.com/CONTRIBUTING.html (under "Spot something off? Want to add some content? Take a look at our contribution guide!")

Found on Google Chrome Version 85.0.4183.121 (Official Build) (64-bit).

Steps to replicate this issue:

1. Right click either of the links mentioned above and select new tab

2. Click "new tab". The page will redirect to the .HTML file.

Recommended fixes: Link to https://docs.ubclaunchpad.com/introduction instead of https://docs.ubclaunchpad.com/introduction.html and https://docs.ubclaunchpad.com/CONTRIBUTING instead of https://docs.ubclaunchpad.com/CONTRIBUTING.html

Unfortunately, this might be a VuePress limitation, since in markdown we link directly to markdown files and - though I swear we have a plugin to drop the trailing .html extension:

Aside, and probably not relevant, but this is enabled on the Netlify side with this config: https://github.com/ubclaunchpad/docs/blob/master/netlify.toml#L7-L32

I managed to include a fix for this in #197
