Maintainer bios: normalize to first person

[Stargator]

Currently, there's only one maintainer with a bio and it's fairly generic. Kytrinyx had an issue opened to suggest changing the bios to first person because:

it feels more friendly/human and less corporate/official

Since that has been back burnered on her end, I figured I'd ask @exercism/dart whether any of you would be willing to update your bios to first person or add a bio that is written in first person.

I like mine the way that it is because it more closely matches bios from other places.

@jvarness Understood. Again, it's not a critical "thing". I'll keep this issue as a reminder for myself to add a bio.
