show TS where to find @canvas/ packages
show TS where to find @canvas/ packages

why:
* to get rid of the TS compiler error and to get types imported
from other packages in ui/shared

refs INTEROP-7137
flag=none

test plan:
* with an IDE that has TS turned on like VSCode or the TS compiler
running
* write an import statement like
`import axios from '@canvas/axios'`
* it should find that import and not error, and should properly
link to its type definitions
