Update semconv scripts to support extended stability levels

[lmolkova]

Erlang uses exact match for stability

weaver registry generate --registry=semtmp/model --templates=templates --param output=lib/incubating/ --param stability=experimental elixir .

It works great for stable level, but we're adopting other levels (open-telemetry/semantic-conventions#1096) in semconv and starting to use development, rc.

You can either leverage new semconv_grouped_attributes helper in weaver

(e.g. here's how Java uses it)

  - pattern: SemanticAttributes.java.j2
    filter: >
      semconv_grouped_attributes({
        "exclude_root_namespace": $excluded_namespaces,
        "exclude_stability": ["experimental"] # experimental here is fine, weaver matches all non-stable things to it
      }) | map({
          root_namespace: .root_namespace,
          attributes: .attributes,
          excluded_attributes: $excluded_attributes
      })

or replace logic inside

Line 18 in 1a8bb51

{%- if params.stability == "experimental" and (ctx.all_attributes | length) > (ctx.attributes | length) %}

to cover other stability levels.

E.g. you might find weaver experimental and other similar helpers useful.

{% if attribute is experimental %}
...
{% if attribute is stable%}
