[MM-39399] Bump min_server_version due to imported server dependency breaking changes

[mickmister]

Summary

There is a breaking change with 5.37 server code, where the plugin will crash if:

• The plugin is importing code 5.37 or later
• The server is running 5.36 or before

This PR downgrades the dependencies of mattermost-plugin-api and mattermost-server. The only change to the plugin source code is a change in the constructor of the pluginapi.Client. We are no longer accessing a plugin.Driver struct to pass to this constructor.

The dependency was originally bumped for the license check. The license check code is very small and has no dependencies, so I copied some code over to this repo to avoid the greater dependency. The license check is still the correct logic.

Edit: I've changed the PR so it just updates the min_server_version

Should we bump the minimum server version to 5.37 to fix this issue? 5.36 is a quite old version that isn't supported any longer according to https://docs.mattermost.com/upgrade/extended-support-release.html.

Do we need a patch release?

Closing in favor of mattermost/mattermost-marketplace#233

[hanzei]

Don't we want to bump the min_server_version for the next release?

[mickmister]

Repoening, as the fix still needs to be applied here, and not just the marketplace.

[hanzei]

Let's simply merge this as the fix is straight forward.
