Relax dependency versions for opentelemetry deps

[mosic]

I ran into this while trying to update opentelemetry_api in this PR: primait/prima_opentelemetry_ex#23

Failed to use "opentelemetry_api" (version 1.1.0) because
  opentelemetry (version 1.1.1) requires ~> 1.1
  opentelemetry_absinthe (version 1.0.0) requires ~> 1.0
  opentelemetry_ecto (version 1.0.0) requires ~> 1.0
  opentelemetry_exporter (version 1.1.1) requires ~> 1.1
  teleplug (version 1.0.0) requires ~> 1.0.0
  mix.lock specifies 1.1.0

I also updated opentelemetry deps and bumped up the version number.

Thanks! I would just bump the teleplug version to 1.0.1 since we are not adding any new features to the library

[mosic]

Fair enough, updated to 1.0.1 👍

@Fs00 Can you merge it as well? UK devs don't have the required permissions in this repo.

Released version 1.0.1 on hex.pm
