Switching dependency bot to renovate

[XSAM]

Problem Statement

• An update for a single dependency across our go submodules would occur in multiple PRs. It is annoying.
• GitHub's dependabot doesn't support docker-compose files. Support for Docker compose files dependabot/dependabot-core#390

Proposed Solution

Switch to renovate

Additional Context

#5244 (comment)

Tasks

• Sunset github dependabot.

This config can be used as a reference: https://github.com/signalfx/splunk-otel-go/blob/main/renovate.json

• this also bumps indirect dependencies (except build directory)
• runs go mod tidy
• ensures that all folders are checked (e.g. test are excluded by default)

e.g.

{
  "$schema": "https://docs.renovatebot.com/renovate-schema.json",
  "extends": [
    "config:recommended"
  ],
  "ignorePaths": [],
  "separateMajorMinor": true,
  "postUpdateOptions" : [
    "gomodTidy"
  ],
  "packageRules": [
    {
      "matchManagers": ["gomod"],
      "matchDepTypes": ["indirect"],
      "enabled": true
    },
    {
      "matchFileNames": ["internal/tools/**"],
      "matchManagers": ["gomod"],
      "matchDepTypes": ["indirect"],
      "enabled": false
    }
  ]
}

@XSAM, I updated open-telemetry/opentelemetry-go-contrib#4579

I don't know why this repo didn't receive any Configure Renovate PR.

FYI, the default config file looks like this

{
  "$schema": "https://docs.renovatebot.com/renovate-schema.json",
  "extends": [
    "config:recommended"
  ]
}

I know but I want to at least make sure that go mod tidy is run and test Go modules are not ignored.

The renovate bot failed to create Renovate PR because it got a 422 Error from GitHub. https://developer.mend.io/github/open-telemetry/opentelemetry-go/-/job/817ca928-01ff-4038-a171-0296c06ab5ad

It fails because we are probably missing this rule in this repo: https://github.com/open-telemetry/community/blob/main/docs/how-to-configure-new-repository.md#branch-protection-rule-renovate
