Minor typo/pasta fixes in blob_sidecar_{index} validation

 The following validations MUST pass before forwarding the `sidecar` on the network, assuming the alias `sidecar = signed_blob_sidecar.message`:
 
 - _[REJECT]_ The sidecar is for the correct topic -- i.e. `sidecar.index` matches the topic `{index}`.
-- _[IGNORE]_ The sidecar is not from a future slot (with a `MAXIMUM_GOSSIP_CLOCK_DISPARITY` allowance) -- i.e. validate that `sidecar.slot <= current_slot` (a client MAY queue future blocks for processing at the appropriate slot).
+- _[IGNORE]_ The sidecar is not from a future slot (with a `MAXIMUM_GOSSIP_CLOCK_DISPARITY` allowance) -- i.e. validate that `sidecar.slot <= current_slot` (a client MAY queue future sidecars for processing at the appropriate slot).
 - _[IGNORE]_ The sidecar is from a slot greater than the latest finalized slot -- i.e. validate that `sidecar.slot > compute_start_slot_at_epoch(state.finalized_checkpoint.epoch)`
-- _[IGNORE]_ The blob's block's parent (defined by `sidecar.block_parent_root`) has been seen (via both gossip and non-gossip sources) (a client MAY queue blocks for processing once the parent block is retrieved).
-- _[REJECT]_ The blob's block's parent (defined by `sidecar.block_parent_root`) passes validation.
+- _[IGNORE]_ The sidecar's block's parent (defined by `sidecar.block_parent_root`) has been seen (via both gossip and non-gossip sources) (a client MAY queue sidecars for processing once the parent block is retrieved).
+- _[REJECT]_ The sidecar's block's parent (defined by `sidecar.block_parent_root`) passes validation.
 - _[REJECT]_ The proposer signature, `signed_blob_sidecar.signature`, is valid with respect to the `sidecar.proposer_index` pubkey.
 - _[IGNORE]_ The sidecar is the only sidecar with valid signature received for the tuple `(sidecar.block_root, sidecar.index)`.
 - _[REJECT]_ The sidecar is proposed by the expected `proposer_index` for the block's slot in the context of the current shuffling (defined by `block_parent_root`/`slot`).
