Double the Requests Memory from Workspace Resources to increase memory available for Java

[felladrin]

Description

Currently, when we create a workspace from https://github.com/gitpod-io/spring-petclinic on Preview Environment, it will trigger an OutOfMemoryError during the Build Task.

This happens because JAVA_TOOL_OPTIONS currently is set to -Xmx134m due to this line which affects GITPOD_MEMORY env var, which in turn is used to set Java's memory here.

This PR increases Preview Environments memory to address this issue. By increasing memory to 256Mi, JAVA_TOOL_OPTIONS becomes -Xmx268m, which is enough to make "gitpod-io/spring-petclinic" to build correctly:
