- Allow triggering of Jenkins jobs that reside in sub-folders, by treating job names containing slashes as query variables.

- Prior to this feature, jobs in sub-folders were not appropriately matched by the Spring framework due to slashes in their path, causing trigger requests to fail.

- Include a new feature flag to determine the usage of the existing endpoint (which uses the job name as a path variable) or an updated endpoint (which takes the job name as a query parameter).
