fix(deps): update module gopkg.in/kyokomi/emoji.v1 to github.com/kyokomi/emoji/v2

[clok]

What does this do / why do we need it?

This will update the emoji module to v2 while addressing this install error:

go: gopkg.in/kyokomi/emoji.v2@v2.2.8: parsing go.mod:
	module declares its path as: github.com/kyokomi/emoji/v2
	        but was required as: gopkg.in/kyokomi/emoji.v2

How this PR fixes the problem?

Use the desired github.com/kyokomi/emoji/v2 module declaration.
