feat: periodic version check and json config

[Matrix89]

This PR builds on top of @schomatis work from #8839, it moves his version checking logic to its own file and adds a ticker which runs it every hour.

Closes #6487

Hey, thanks for triggering the CI. I've synced examples/kubo-as-a-library/go.mod with go.mod and added the version check command to the commands test, I don't know if the other workflow failures are related.

Is there an easy way to run workflows locally(act doesn't seem to work)?

Thank you @Matrix89, I'll try to review and squeeze this into 0.30, the sooner we ship the notice the better.

If you want to run tests locally, you get 90% of them by running cd test/cli and go test ./.... Some sharness tests are flaky, but the one below suggest a panic:

To expedite this PR I'll look into this later today, but will timebox and let you know if I've run out of time.

TODO for self

• fix panic from CI
• UX
  • move warning to a logger, like we already do with provider warning in core/node/provider.go
  • link to releases page
  • ability to disable check
• future-proof / defensive programming
  • disable check when ipfs daemon --offline
  • test with custom Routing.Routers
  • (aka fix or disable when no WAN/LAN DHT)

⚠️ A NEW VERSION OF KUBO DETECTED

This Kubo node is running an outdated version (0.21.0).
63% of the sampled Kubo peers are running a higher version.
Visit https://github.com/ipfs/kubo/releases or https://dist.ipfs.tech/#kubo and update to version 0.29.0 or later.

Lgtm.

Had to moved some things around and fix panics with custom routers. Listed issues are no longer happening, and it's more future-proof. Added docs and changelog.

Looking at https://github.com/probe-lab/network-measurements/blob/main/reports/2024/calendar-week-23/ipfs/README.md#kubo made me adjust min-fraction to 5% to start showing notification bit faster.

In this form it should be a low risk quality of life improvement, so planning to include it in 0.30 (#10436).

Will keep PR open for a few more days, just in case someone wants to drop feedback.

TODO from reviews

configuratbility

• replace env variable with Version.RunSwarmCheck (Flag)
• while at it, add Version.Suffix (optionalString)

[lidel]

Pushed:

• cosmetic refactor that adds proper JSON configuration under Version.* namespace, and also moves related agent-version-suffix under that, making it easier for people using Kubo in their infra to identify their nodes
• docs and changelog

Merging to include in 0.30.0-rc1 (#10436) and gather feedback.
Once again, thanks for poking at this @Matrix89 ❤️
