feat(dev-ux): go.mod update tool

[p0mvn]

Background

Currently, when we update one of:

• osmoutils
• osmomath
• x/ibc-hooks

our local tests pick up the changes from the modules right away. Howevever, the e2e test depends on the go.mod being correctly tagged with the latest version.

As a result, an engineer has to manually run the following command to update the root go.mod:

go get < module > @< commit hash >

go mod tidy

We need a way to automate this process.

Suggested Design

The end goal of this is the following:

• detect if osmoutils, osmomath and x/ibc-hooks modules were updated in a PR
• if so, auto-open PR to your branch with global go.mod updated to the deps in your branch

I propose splitting this into the following steps / PRs:

1. Create a script that when run, does the following:

# detect current branch

go get github.com/osmosis-labs/osmosis/osmomath@< branch hash >
go get github.com/osmosis-labs/osmosis/osmoutils@< branch hash >
go get github.com/osmosis-labs/osmosis/x/ibc-hooks@< branch hash >

go mod tidy

Note that for this to work, the current branch must be pushed to remote.

2. Create a CI job that detects if any of osmomath, osmoutils, x/ibc-hooks` had any changes.
   • If so, it runs the script and opens a PR against your branch with the changes from script 1 applied.

Acceptance Criteria

• The process of updating go.mod is fully automated
• Successfully executes every time when an update to osmomath, ``osmoutilsorx/ibc-hooks` is made
• Auto-opens a PR against developer's branch with the go.mod changes
