fix(login): prettier setup (#11798)

# Which Problems Are Solved
Invalid formatting in the login codebase due to invalid prettier
configuration

# How the Problems Are Solved
Fxed .prettierignore wildcards for login source files

# Additional Changes
Removed .prettierrc file because there is already a prettier.config.mjs
file

# Additional Context

apps/login/src/lib/api.ts
