Update the common versions of io.micrometer* instead of having spring specific versions #11378
Description
As part of this PR, there were two spring specific dependencies declared in the external_dependencies file.
spring_io.micrometer:micrometer-registry-azure-monitor;1.3.0
spring_io.micrometer:micrometer-core;1.3.0
Whenever possible it's recommended to update the common dependency rather than declare area specific dependencies. The common io.micrometer* external_dependencies should all three be updated to 1.3.0 instead of having spring specific ones. Since Cosmos is the only other one using this, @kushagraThapar had commented on the PR this OK to update but wasn't a blocker to get the PR in.
