Wrong chrony stratum (doc has updated, AgentBaker has not)

[Artoria2e5]

What happened:
A lot of files have

refclock PHC /dev/ptp0 poll 3 dpoll -2 offset 0

What you expected to happen:

refclock PHC /dev/ptp_hyperv poll 3 dpoll -2 offset 0 stratum 2

like in current version of https://learn.microsoft.com/en-us/azure/virtual-machines/linux/time-sync should be instead present. Or if you don't want ptp_hyperv, ptp0 is okay; what matters is stratum 2

How to reproduce it:
Use grep on the existing source files.

Anything else we need to know?:
Wrong stratum leads to user confusion in https://www.mail-archive.com/chrony-users@chrony.tuxfamily.org/msg03770.html.

Environment:

• AgentBaker version: HEAD
• Kubernetes version (use kubectl version):
• OS (e.g. from /etc/os-release):
• Kernel (e.g. uname -a):
• Install tools:
• Others:

This doesn't make any difference for our default configuration due to the lack of any other time source, as discussed in this reply. However, it would be worthwhile to pull in the udev rule and update the configuration in the event that someone does add servers without realizing that they would need to adjust stratum.
