[JoelJacobStephen]

Ticket

Closes HFE-203

Description

This PR introduces the following features and fixes to the Hoppscotch App and Hoppscotch CLI

Features Added:

• Added the ability to export single environment variables from the Hoppscotch App
• CLI can now accept environment variables from the format in which the Hoppscotch App exports.
• Introduced Zod package into the Hoppscotch CLI to check the validity of the formats for the Environment variables.
• CLI now informs the user that bulk environment export is not supported by the CLI when the file matches the bulk export format.

Issues Fixes:

• Fix the malformed environments error when importing a environment file that was exported from the Hoppscotch App to the CLI.
• Fix the issue when there are are no error messages being given when it is a malformed environment error

Objectives

• Add ability to export single environment variables
• On export of environment variables, remove id from environment and send only the name and variables.
• The CLI should be able to receive the format that is exported when exporting environment variables from the Hoppscotch App.
• Fix the malformed environments error when importing a environment file that was exported from the app to the CLI.
• CLI should inform the user that bulk environment export is not supported by the CLI when the file matches the bulk export format.

Note

Requires changes to the Documentation as the CLI can now accept the format that the Hoppscotch App uses to export environment variables. The new format must be mentioned in the documentation. Also need to mention that bulk environment export is not supported by the CLI.

Checks

Exporting of only personal environments is done we need to implement the same for team environment as well

Can you verify if the CLI accepts the environment exported as a whole? It was throwing when I gave it a shot.

Looks good, left a few minor comments. As discussed, let's add tests for the changes. Also, please ensure to raise a PR for the docs updates required.
