Update logo of Tank with new Intuit's logo

[anaghesh-muruli]

The existing logo has 2 problems:

1. Has old Intuit logo
2. Goes against the logo guidelines (https://assetlibrary.intuit.com/content/oial/language-masters/en/asset-library/brands/intuit-brand/how-we-look/intuit-logo.html)

The existing log was created before the guidelines where written.
