Update OTP versions for GH Actions

[jacekwegr]

This PR updates the Erlang/OTP versions used in GitHub Actions CI workflows to the latest versions: Erlang/OTP 26 and 27.

• Erlang/OTP Version Update: Most of the CI jobs now use the latest Erlang/OTP versions (26 and 27).
• Ubuntu Xenial Package Job: The job for the Ubuntu Xenial package has been updated to the newest version of Erlang/OTP 25 because versions 26 and 27 aren't available yet.

This update keeps the CI pipeline up to date with the latest Erlang/OTP versions.

Successful CI job run: https://github.com/esl/MongooseIM/actions/runs/10526511796
