Add gitlab-elasticsearch-indexer to asdf-combine

What does this Merge Request do and why?

Adding gitlab-elasticsearch-indexer version so the required versions are used when gdk update is run

Issue reported in slack: https://gitlab.slack.com/archives/C2Z9A056E/p1651758453797859

The gitlab-elasticsearch-indexer fails to compile when I run rspec. There’s a bunch of compile: version "go1.17.9" does not match go tool version "go1.17.6" in the output.

possibly related to merge of: gitlab-elasticsearch-indexer!151 (merged)
