Create issue and merge request templates for updating VSCode Fork

MR: Pending

Description

As a VSCode Fork maintainer, who periodically needs to upgrade the VSCode Fork to a newer version, I want an issue template and a merge request template that I can use to streamline the process of scheduling upgrades. The goal is reducing the amount of decision making, and repetitiveness of creating issues and merge requests every time that we upgrade the VSCode Fork.

Acceptance Criteria

• Create an "Upgrade VSCode Fork {{version}}" issue template.
  • The template has a placeholder for the VSCode version.
  • The template applies the required labels per the Web IDE development process.
  • The template requires linking to the "Upgrade VSCode Fork Merge Request".
• Create an "Upgrade VSCode Fork {{version}}" merge request template.
  • The template has a placeholder for the VSCode version.
  • The template applied the required labels per the Web IDE development process.
  • The template contains a section to share "Integration testing" results for The Web IDE and Workspaces.
  • The template contains a section to describe Breaking Changes introduced by the newer version.
