Update tycho version from 3.0.0 to 3.0.5

I think this fixes crashes from the presubmit for unknown commit:

```
Error: Exception in thread "main" java.lang.NoSuchMethodError: 'java.lang.String org.eclipse.equinox.p2.core.IProvisioningAgent.getProperty(java.lang.String)'
	at org.eclipse.equinox.internal.p2.artifact.repository.simple.SimpleArtifactRepository.getAgentPropertyWithFallback(SimpleArtifactRepository.java:813)
	at org.eclipse.equinox.internal.p2.artifact.repository.simple.SimpleArtifactRepository.getMaximumThreads(SimpleArtifactRepository.java:1012)
```

I tested a PR with these changes and it was clean [1], so either this helps or
it was a transient issue, but either way this shouldn't hurt.
