🐛 Navigation links in the API page are broken

Describe the bug
The links in the parse-server API page are broken. Clicking on them changes the page hash but doesn't scroll to the associated section.

To Reproduce
Steps to reproduce the behavior:

1. Go to the webpage
2. Scroll down to the nav links below the sponsors
3. Click on any of the links, none work.

Expected behavior
Clicking on the link should scroll to the associated section.

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: Ubuntu
• Browser: Brave
• Version: Version 1.28.106 Chromium: 92.0.4515.159 (Official Build) (64-bit)

Smartphone (please complete the following information):

• Device: [e.g. iPhone6]
• OS: [e.g. iOS8.1]
• Browser [e.g. stock browser, safari]
• Version [e.g. 22]

Additional context
One solution is to simply add the id attribute to all the headings so that the browser handles the scrolling without any additional config. For example for the "Using Environment Variables" link, the hash changes to #using-environment-variables, so the associated <h2> in the page should have id="using-environment-variables". This should be done for all the nav links.

Open the parse-server API page and inspect the source that generates its navigation links and section headings. Compare each link hash, such as #using-environment-variables, with the corresponding heading and ensure the generated page scrolls to every linked section. Verify the result by clicking the navigation links on the API page.
