docs: address Copilot grammar review on ospf and vpp ipsec

- ipsec.md: "to speed-up" -> "to speed up"; drop article in "creates a
  corresponding SAs and policies"; "there routes" -> "these routes".
- ospf.md: "Cost calculation wireguard interfaces" -> "Cost calculation
  for WireGuard interfaces".
