add pekko-connectors-bom

[pjfanning]

We have BOMs for Pekko(Core) and Pekko-HTTP.

• https://repo1.maven.org/maven2/org/apache/pekko/pekko-bom_2.13/1.0.2/pekko-bom_2.13-1.0.2.pom
• https://repo1.maven.org/maven2/org/apache/pekko/pekko-http-bom_2.13/1.0.1/pekko-http-bom_2.13-1.0.1.pom

I think it useful to have one for Pekko-Connectors.

Looks good, Thanks.

If we have a BOM that records all modules(more tha this), it will be better, but it will come with higher maintenance costs.

I have https://github.com/pjfanning/pekko-libraries-bom. The SBT bill-of-materials plugin can only handle projects in same repo. My project is easier to maintain if the main pekko repos have BOMs that I can more easily aggregate.

It sounds reasonable. Let's move forward.
