Update Inter font and set display: swap (#2000)
The version of Inter is updated to use a variable font, which is supported widely among modern browsers.

Using `display: swap` means that the browser will render the text of the spec even before Inter is loaded, making the website appear to load faster on mobile.

Allow the browser to use the local Inter font if it exists.

# Fonts
## Inter.css
`Inter.css` is a local copy of
https://fonts.googleapis.com/css2?family=Inter:opsz,wght@14..32,100..900&display=swap, modified to pull
font files (`.woff2`) from local sources. It was created
using `download_google_fonts_css.py`.
## download_google_fonts_css.py
`download_google_fonts_css.py` is a script that takes a google fonts CSS URL, downloads
the file and linked fonts, then saves the fonts locally along with a modified CSS file to
load them. Example call:
```sh
python3 download_google_fonts_css.py \
"https://fonts.googleapis.com/css2?family=Inter:opsz,wght@14..32,100..900&display=swap" \
../../../static/fonts \
../../fonts
```
Which would pop out a `Inter.css` file that should be `@import url("Inter.css")`d
somewhere in the site's SCSS (currently in
[/assets/scss/_variables_project.scss](/assets/scss/_variables_project.scss)).
Re-running the script and committing any new files is only necessary when a desired
font updates (not very often), or we want to change the font we're using. In that case,
remove the existing font files at `/static/fonts/*.woff2` and re-run the script with a
different URL.
