chore: update clr formula

[thelostone-mc]

Based on the changes made by @frankchen07 after discussing with vitalik

@frankchen07 I haven't commented out the one off contribution -> let me know if that is something you would still want to remove. Cause in that case if a grant has no contributors -> it'll appear in the UI that contributing any amount would have a matching 0 as pair could not be formed

fixes: #5425

@thelostone-mc - I think for the sake of making an accurate QV statement, if a grant only has 1 donator, the CLR match will be 0, since that's how we're performing pairwise matching.

The downside risk here is the "potential match" is marketing as well, just tough to say how effective it was compared to blasting it out on twitter and getting Vitalik's help.

I say we trend towards being true and accurate to QV in the front as we are in the behind the scenes calculations, and if we want to later add something saying "get a friend to donate too and you'll get a match!" we can salvage the marketing situation.

[frankchen07]

LGTM - just make sure we comment out the snippet of code to ensure if no pair = no contribution.

@frankchen07 done ^_^
