[allure-jest] Add API to write environment info

[maks-rafalko]

Is your feature request related to a problem? Please describe.

Currently, it's impossible to add environment information, displayed on the main page of Allure report: https://allurereport.org/docs/jest/#environment-information

Describe the solution you'd like

I would like to make it working out of the box in allure-jest reporter, for example adding this information in Jest configuration (https://allurereport.org/docs/jest-configuration/#allure-jest-configuration) or just by calling some public method on global.allure

Describe alternatives you've considered

N/A

Additional context

Currently, there is a method writeEnvironmentInfo() on AllureRuntime interface, but this is an internal thing which is not available for public usage in allure-jest.

Related to more common request: #181

fixed in #1021

Though it would be nice to have .writeEnvironmentInfo({...}) public API for Jest, as currently we write there dynamic data, not only data from jest config. In referenced PR I see in allure-jest test only the case with config.
