Update intel-microcode to latest upstream release 20200616 to fix possible regression in 06-5e-03/0x000506e3

[Alex Murray]

As a result of https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1882890 the microcode for 06-4e-03 was reverted from the most recent intel-microcode release to the previous one - Intel has subsequently released a new upstream release https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/releases/tag/microcode-20200616 which includes this revert *as well as a revert for the 06-5e-03/0x000506e3 microcode too*. This should also be updated in Ubuntu to ensure we do not suffer any unexpected regressions on these platforms too.

Debian will also issue such an update, but we have both "works" and "fails" reports of 0x506e3.

We're waiting for some more data re. 0x806eX and 0x906eX, but the situation there is far less clear.

The Eoan Ermine has reached end of life, so this bug will not be fixed for that release

This is now obsolete - we recently updated intel-microcode to the most recent 20201110 release.
