build (deps): upgrade opentelemetry to 1.62.0 to patch CVE-2026-45292

[blakeli0]

Upgrades opentelemetry.version to 1.62.0 to address CVE-2026-45292 (GHSA-rcgg-9c38-7xpx). This repo is actually NOT affected by this vulnerability but it is a good practice to upgrade it so it does not show up in customers' reports.

Separately, removed unnecessary version declaration of opentelemetry in Spanner.

Code Review

This pull request updates the OpenTelemetry version to 1.62.0 across several Maven configuration files. It also introduces a dummy comment in LoggingUtils.java to trigger the CI pipeline. The feedback advises removing this dummy comment to avoid unnecessary noise in the codebase, suggesting cleaner alternatives like empty git commits to trigger CI.

Do we care about this sample's version?

Line 40 in 8183d08

<opentelemetry.version>1.57.0</opentelemetry.version>

I don't think it matters much but it is more of a best practice to make all versions update together.

Separately, I also briefly looks into if we can remove the version from bigquery samples as well. I think we probably can because it is not used in between the region tags. Do you have more info about how it is used (not in scope of this PR)?
