Leaderboard crashes when node version is unknown

[GustavoStingelin]

The leaderboard crashes when the fork observer returns node info with an unknown version string, because getVersionNumber assumes the string contains : and ends up indexing into undefined.

Reference:

warnet-web/src/helpers/index.ts

Line 73 in aec0175

export const getVersionNumber = (version: string) => {

export const getVersionNumber = (version: string) => {
  // get the version number from the version string
  return version.split(":")[1].split("/")[0].split("(")[0] ?? false;
}

It appears to happen when the fork observer is restarted and loses part of its cached state.

@TheMhv was running the Warnet Battle during BDL2 at Vinteum and may be able to share additional context or logs that clarify what is being returned in this scenario.

In any case, it would be good to handle this more defensively so the page does not crash when an unexpected or unknown version string is received.
