Fix nits in feature gates page 

Issues fixed by this PR:

- Link in PodDeletionCost is wrong.
- Default value for APIResponseCompression since 1.16 should be true
- Default value for KubeletPodResources in 1.13, 1.14 should be false
- CSIVolumeHealth is an Alpha feature introduced in 1.21, not graduated or deprecated
- EndpointSlice is still Beta in 1.20
- EndpointSliceNodeName is only GA’ed in 1.21
- IndexedJob is an Alpha starting 1.21, not graduated or deprecated
- KubeletPodResources has been GA’ed in 1.20, thus should be removed from the first table
- RequestManagement was deprecated in 1.17 and replaced by APIPriorityAndFaireness
- Several field names are incorrect (e.g. `appProtocol`, `internalTrafficPolicy`, `loadBalancerClass`)
- SCTPSupport should be removed from the first table because it was GA’ed in 1.20.
- ServcieAppProtocol is Beta until 1.20
- StreamingProxyRedirects  is GA’ed in 1.19, not deprecated
- No description for ValidateProxyRedirects is provided
- VolumeCapacityPriority is an Alpha feature introduced in 1.21, not graduated
- The order of VolumePVCDataSource is wrong in the table
- No description provided for Initializers
- The deprecated status should not be repeated in the description since it is already indicated by the table in which a feature is listed.
- No description is provided for RequestManagement
