Reproduction steps

fontweight typo

1. Navigate to and click on any contributor's card
2. Hover over the 'Contributor Spotlight' text and click inspect to open devtools
3. Notice the <h5> class shows a custom prop (fontweight = 500) instead of no prop (which would mean MUI identified it as a prop part of the Typography component)

The real font-weight applied is 400 instead:

Proposed fix: Just a typo. Needs to be camelCase (fontWeight rather than fontweight)

Expected Results

1. fontWeight prop should be applied so font-weight: 500 on h5 title

Actual Results

fontWeight is 'fontweight', causing a default font-weight of 400px to be applied instead on the text
