With Cilium v1.16 we raised & clarified the minimum kernel requirement, adjust the docs accordingly.

Cilium now requires a 5.4 kernel, remove this stale dependency from the
docs.

Note that RHEL8 also contains the relevant kernel changes, see
cilium#34491.

EGW and VTEP depend on HaveLargeInstructionLimit(), and thus required
a 5.2 kernel.

As Cilium now requires a 5.4 kernel, the requirement is always satisfied.
RHEL8 also provides HaveLargeInstructionLimit(), and we even fatal on
startup if this capability is not available.

Later in the doc we even describe how to configure the feature with
KPR=off.
