konstraint doc randomly reorders parameters

[zephyrdb]

We run konstraint doc a lot, and we just added our first policy with multiple parameters. The parameters are sometimes randomly reordered in the policies.md file, which is annoying and means I end up running konstraint doc again until they stay the way they were. I traced the problem here:

konstraint/internal/commands/document.go

Line 275 in 67e69cd

for param, config := range parameters {

Go map elements are returned in random order. It would be helpful if they could be sorted before this line.

Thanks.
