Update Armeria to 1.32.6

This Armeria patch version was requested explicitly:
line/armeria#6733

Fixes #6271 since the current Ameria version is affected by a couple
of bugs (see comment #6271 (comment)).

Furthermore, replace io.micrometer.core.lang annotation which is going
to be deprecated in Micrometer 1.16.0 - see release notes:
https://github.com/micrometer-metrics/micrometer/releases/tag/v1.16.0.
