feat: adds support for blue-chip endpoint

[joaosantos15]

Explanation

• What is the current state of things and why does it need to change?
  • Currently the token-search doesn't support the Portfolio APIs blue-chip endpoint. We need to add support for it, because the mm-mobile requires it.
• What is the solution your changes offer and how does it work?
  • Very simple, we just add support for the new endpoint.
• Are there any changes whose purpose might not obvious to those unfamiliar with the domain?
  • No.
• If your primary goal was to update one package but you found you had to update another one along the way, why did you do so?
  • n/a
• If you had to upgrade a dependency, why did you do so?
