gitlab-runner 14.10.1 fails to clone a repo configured with a `https` repo URL
## Summary
gitlab-runner version 14.10.1 fails to clone a repo configured with a `https` repo URL, stating `HTTP Basic: Access denied`.
## Steps to reproduce
1. Configure a docker runner with a `https` URL in `/etc/gitlab-runner/config.toml` like so:
```
[[runners]]
name = "docker"
url = "https://gitlab.example.com/"
token = "..."
tls-ca-file = "..."
executor = "docker"
# ...
```
2. Run a CI job.
## Actual behavior
gitlab-runner changes the protocol to non-TLS `http`, then fails to clone the repo, stating
```
remote: HTTP Basic: Access denied
fatal: Authentication failed for 'http://gitlab.example.com/internal/example-project.git/'
```
## Expected behavior
The runner should use the repo URL as is, including the `https` protocol, like gitlab-runner 14.10.0 did.

### Used GitLab Runner version
```
Version: 14.10.1
Git revision: f761588f
Git branch: 14-10-stable
GO version: go1.17.7
Built: 2022-05-02T16:08:41+0000

```
## Possible fixes
Adding a `clone_url` makes cloning in the above scenario work again:
```
clone_url = "https://gitlab.example.com/"
```
