docs(dependency pinning): drop reference to motto

[HonkingGoose]

Changes

• Drop reference to motto "Flexible, so you don't need to be" because we don't use that motto elsewhere

Context

We don't use the motto

I don't see us using this motto anywhere. It's not in the:

• repository readme
• docs repository readme
• search for flexible on the published docs (except in the file I'm changing with this PR 🙃)
• GitHub app installation homepage

Reference new motto/slogan?

I think this statement is more like a slogan, and we actually use it in the repository readme and docs homepage. But the slogan is not about customization:

Automated dependency updates. Multi-platform and multi-language.

Or we could reference the How you like it slogan/motto from the docs homepage:

🎯 How you like it

You can customize the bot's behavior with configuration files.

What do you want me to do?

Let me know what you want:

1. Drop motto reference
2. Change it to something else
