Public bug reported:

[Impact]
new upstream release; usual vendored dependency updates per Go MIR policy (vendor/ directory is automatically generated by go mod vendor based on go.mod).

Targeted releases: noble, jammy

[Test plan]
* Test suite passes

* Deploy Azure CVM and TPM FDE
* Upgrade to this new package and reboot
* Boot should be successful
* Double check bios_measurements_log to ensure that the newly update shim was used for boot (https://github.com/canonical/tcglog-parser/tree/master/tcglog-dump can be used to extract checksum of the shim binary used at boot and compared to the one shipped in nullboot)

* CPC - build new image with nullboot preinstalled, and attempt to
register and boot such an images as first time.

We have set block-proposed to allow testing in {noble,jammy}-proposed to
be carried out before migration to  release pockets.

[Where problems could occur]
Resealing of Azure CVM machines could fail and they would need to be unlocked with a recovery key.
