[charts] Fix timezone regression in charts

[markov00]

Summary

We introduced a regression that causes time series charts without a timezone configured to be rendered with UTC by default instead of the local timezone.
We already have fixed the bug in charts here and the dependency is updated already in versions 7.17, 8.0.1, 8.1 but we are missing 8.0 since we are really close to the next RC.

This PR brings back the default behavior marking all time-series with no timezone parameter using the local timezone.

I will forward these changes to 7.17, 8.1, main in a different PR to land this PR sooner as it has a higher priority

Merging the same PR as #123478 fixing the conflict in the Uptime chart that caused the commit to be reverted
