Update goreleaser to release statically linked binary

[kaustubhkapatral]

Summary

Add support in goreleaser to release statically linked binary when a new tag is pushed.

Problem Definition

As umee has cosmwasm integration in it, if a binary is built using the regular build instructions of make build or make install on one host, it can't be used to run on a different host before downloading the libwasm file on the new host. The same issue is present for the binary which gets released when a new tag is released. A separate set of instructions is always provided to the validators to make sure they update their libwasm file if they use pre-built binary. Ex:- the libwasmvm update section present under Validators header present here:- https://github.com/umee-network/umee/releases/tag/v6.4.0

Proposal

Update goreleaser to build and release statically linked binary that does not require any libwasmvm prerequisite setup.
