[vscode Concourse extension] Property 'commit_message' not recognized for semver resources

[ThibaultDelaune-pro]

Describe the bug
The vscode Concourse extension raise an error when a semver resource has a 'commit_message' property set for git driver.

To Reproduce

resources:
- name: my_resource
  type: semver
  source:
    driver: git
    uri: ((repo_uri))
    private_key: ((private_key))
    branch: master
    file: version.txt
    commit_message: "[skip ci] my commit message"

cf. https://github.com/concourse/semver-resource

Confirmed that 'commit_message' is missing from our schema and should be added.

In the same part of the schema and the above linked docs I also found that a property skip_ssl_verification is missing from our schema. So I will add support for both of these:

• commit_message
• skip_ssl_verification

Sample code (based on above sample but addinng skip_ssl_verification to it as well).

resources:
- name: my_resource
  type: semver
  source:
    driver: git
    uri: ((repo_uri))
    private_key: ((private_key))
    branch: master
    file: version.txt
    commit_message: "[skip ci] my commit message"
    skip_ssl_verification: true
