[Dev] Add dependabot configuration to remove duplicated labels

[raulcd]

Describe the enhancement requested

As discussed here: #14761 (comment)
There are currently some duplicated labels for language like javascript and Component: JavaScript due to dependabot using the default javascript one.
We could remove the duplicated labels by adding custom configuration to dependabot to use the Component: lang ones.
See here: https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/configuration-options-for-the-dependabot.yml-file#labels

Also, since we can also set the prefix of the commit message, it maybe able to merge without having to edit the message manually (like Bump xxx from yyy to zzz -> MINOR: [COMPONENT] Bump ...).
