fix(sagemaker): Disable start/stop button for intermediate state of the space

[bhavya2109sharma]

Problem

• Users could click start/stop buttons on SageMaker spaces while they were already in the process of starting or stopping.

Solution

• Disables start/stop buttons when SageMaker space is in STARTING or STOPPING state to prevent invalid operations during state transitions.
• Added pending state check in getContext() method
• Returns specific context values for pending states (smusSpacePendingNode/awsSagemakerSpacePendingNode) in package.json [openRemoteConnection]

from above sagemakerSpace.getContext() it seems that a Sagemaker space must be one of those 3,

• awsSagemakerSpaceRunningNode
• awsSagemakerSpacePendingNode
• awsSagemakerSpaceNode

which means
viewItem =~ /^(awsSagemakerSpaceRunningNode|awsSagemakerSpaceNode)$/ && viewItem != awsSagemakerSpacePendingNode"
is equivalent to just
viewItem =~ /^(awsSagemakerSpaceRunningNode|awsSagemakerSpaceNode)$/

Maybe we can make this simpler?
