Launchable: Disable request retries when a timeout exception occurs (#12877)

When a Launchable server is unstable, a ReadTimeoutException occurs in the Launchable CLI. In such case, the Launchable CLI retries requests, which slows down CI execution. In this PR, I configured the environment variable SKIP_TIMEOUT_RETRY to disable retry attempts on requests(Link: https://github.com/launchableinc/cli/pull/992).

```
