Promote Carlos (@nzlosh) to Senior Maintainers

[arm4b]

Carlos (@nzlosh) is a StackStorm maintainer for years, was a release assistant for v3.7.0, fully led a v3.8.0 and now helping with the v3.8.1 patch release. In a meantime, he already participates in coordinating needs for the future v3.9.0 release like Python deprecation and adding new versions and initiatives to support the different OS flavors.

• v3.8.0 release tracker community#110
  • Plan: Python 3.8 support for Ubuntu 20.04 community#68
  • Add Ubuntu 20.04 (focal) support st2-packages#700
  • coordinating and implementing complex multi-step/multi-level projects
• TSC Meeting (12th Sept 2023) community#124
• TSC Meeting Minutes (10th October 2023)  community#126
• Add RBAC to action-alias help api. #6022
• StackStorm v3.9.0 Project Board

He's one of the most experienced StackStorm Maintainers and currently the most active TSC member in Slack, Github Issues, reviewing core stackstorm/st2 Pull Requests, helping not only newcomers to get started but also with the hard questions and workflow cases in the Github Q/A and Discussions, making the community alive and keeping it afloat when others are away.

He's also an author of https://github.com/nzlosh/err-stackstorm, a st2chatops errbot implementation written in Python.

Being an active member of the TSC meetings, he's asking the right questions and prioritizing what's important for the project and eventually is one of the drivers to implement these initiatives. Today's StackStorm OpenSource operation wouldn't be possible without Carlos involvement.

Thank you for all the hardest maintenance work and StackStorm is lucky to have you @nzlosh onboard!
