feat: outdated version notifier (spawn + local-ic)

[reecepbcups]

closes #155
ref: strangelove-ventures/interchaintest#1152

Summary

When a package is out of date (local-ic, spawn), we need to notify the users. This should only be run 1 time per day as it's a heavy operation.

Reason

When Matija was having spawn ICS issues, he was running local-ic v8.2.0, which did not have ICS support. So it was not apparent that a newer version was needed. This will resolve that issue both for spawn & local-ic. Same is useful for future spawn releases (could attach release notes into the binary itself too)

Ideal refactor

Ideally the makefile installer can automatically pull latest (i.e. make get-localic auto pulls v8.4.0, or v8.5.0, etc). Or this can be done within spawn? need to think on the UX here

TODO

• Notify users packages are out of date
  • spawn
  • local-ic
• Easily download latest
  • local-ic
  • spawn
• Package the
  • changelog into the spawn bin? spawn changelog latest, show markdown in terminal
  • Package documentation into spawn bin? spawn docs kind of like man

local-ic version added upstream. if you get-localic it sets the version right, but upstream only go install ./...'ed it. So if the version command is found, it's v8.5.0

Will fix this in v8.6.0
