I've removed most of Spectrum links, but I'm running into a layout issue involving the support links in Docusaurus, which I'm not very experienced with. When removing a link, the two rows no longer have three items each, and I get this unnatural layout where the second row is different.

One thing I've noticed is that we're giving more than three items to <GridBlock layout="threeColumn" align="left" />, which is only supposed to take three. However, even if I split this into two GridBlocks, I can't seem to get the second row to be left aligned.

I'm not sure 😬

@alexkrolick Would you mind taking a look at this issue if you have time?

Alternatively, I'd be ok with leaving the Spectrum link on the help page until we figure this out, as long as @kentcdodds is ok with it.

Meh, let's just merge it. We can fix it later.

@nickmccurdy sorry I missed this.

Yeah, I think we got lucky with the layout aligning in the right number of columns. I recall trying a few different combos (like center-alignining different things, and different column counts) but the layout never really looked that great. Feel free to change it up.
