Issue:
`push` does not send params for lightweight monitors
When pushing lightweight project monitors, it does not include the params defined in either `synthetics.config.ts` or from `--params`.  With the implementation added in https://github.com/elastic/kibana/issues/147467, that means the behaviour is different between browser monitors and lightweight monitors.

i.e. The `push` command should also include the params defined as they can be for browser monitors (config file, `--params`) when sending to Kibana.  The priority of the solution should be the same as for browser monitors (see https://www.elastic.co/guide/en/observability/master/synthetics-params-secrets.html#synthetics-basic-params), i.e.

1. Global params in Kibana
2. Then `synthetics.config.ts`
3. Then `--params` defined in `push`

Ensure the order remains consistent and as defined above with both browser and lightweight monitors after this change.

Pull request:
feat: support params for lw monitors with push
+ fix #725 
+ Add support for pushing params for Lightweight monitors when used in
    - Synthetics config file 
    - CLI flags `--params {"foo": "bar"}`
 + Added a backwards compatibility check to drop `params` config if the push is performed on stack `<8.7.2`. 
+ Check the changes with Kibana PR - https://github.com/elastic/kibana/pull/157226
