ado2gh expects a team name in URL

## Description

After creating a repo in ADO, the repo URL looks like this `https://dev.azure.com//_git/`.

However, ado2gh cli seems to expect the team name to be part of the repo URL, such as:
`https://dev.azure.com///_git/`

The URL returned in the error message (containing the team name) does not exist and the command fails with "source repository does not exist or you do not have permissions".

Unfortunately the cli forces the parameter `--ado-team-project` to be specified. Then even if I specify an empty string `''`, the result is still `https://dev.azure.com///_git/` which is even more incorrect.

## Reproduction Steps
Assuming you have admin on both ADO and GH, and PATs for both tools loaded on the env vars:
1. Create a git repo in ADO
2. Run: `gh ado2gh migrate-repo --ado-org --ado-repo --github-org --github-repo --ado-team-project `
