refactor(x/ecocredit): remove info suffix from queries

[ryanchristo]

Description

Ref: #1029

As a follow up to #1029 and to align with how we write queries elsewhere, this pull request removes the Info suffix from the queries and commands (not from the query response types, which should include the Info suffix).
