feat(cli): add support for request variables

[jamesgeorge007]

Description

This PR adds support for request variables in the CLI. Request variables will have the topmost priority, meaning they will be preferred over any environment variables sharing the same name.

Closes HFE-552.

Changes

• New getResolvedVariables() helper function added under ~/utils/getters.ts that takes in the list of request variables and environment variables for a session and returns a resolved list of variables where keys sharing the same name from environment variables are removed ensuring request variables take priority.
• Relevant instances are updated to account for request variables, alongside environment variables via the above helper function.
• Relevant test updates and associated fixture additions.
• Bumps CLI version to 0.11.0.

Notes to reviewers

Steps to verify

Navigate to the hoppscotch-cli package path locally, and run pnpm build. Run the collection via:

secretBasicAuthPasswordEnvVar=password  bin/hopp.js test <collection_export_file_path> --env <environment_export_file_path>

secretBasicAuthPasswordEnvVar being a secret environment variable, can either be supplied along with environment variables for the session as above or specifying the value field in the environment export file.

The collection and environment export files added under test fixtures can be used to verify the behaviour comprising relevant tests covering various scenarios where a request variable comes into play:

• Ignores inactive request variables.
• Usage alongside environment variables where request variables take priority and ensure support for recursive resolution.
