Add a shortcut integration

[vanilevsky]

Summary

The development work done was primarily focused on integrating a new shortcut feature into the existing codebase. This involved creating new functions, updating existing ones, and writing tests to ensure the functionality works as expected. The changes were made across six files, including the addition of a new file.

Changes

• .github/pull_request_template.md
  • Introduced a new file 'gpt-updater' for updating the GPT (Guid Partition Table).
• README.md
  • Expanded the description of the description command to include a new --shortcut-url option.
  • Added a new section on Templates, explaining how to customize the default pull request description.
• cmd/description/main.go
  • Introduced a new import for a 'shortcut' package.
  • Added a new option for a 'ShortcutBaseURL'.
  • Introduced a new 'descriptionInfo' variable.
  • Modified the 'run' function to check if a pull request already has a generated description.
  • Modified the way the completion and Jira ticket information are generated and stored.
  • Introduced a new function to build shortcut content if a 'ShortcutBaseURL' is provided.
  • Modified the pull request update process to use the new 'descriptionInfo' structure.
• description/description.go
  • Added a new constant string placeholders.
  • Introduced a new struct type Info.
  • Added several new functions.
  • Modified the BuildUpdatedPullRequest function to construct a new pull request description based on the provided Info struct.
  • Introduced the IsDescriptionFinished and needToUpdateByPlaceholder functions to check if a pull request description contains certain placeholders.
  • Imported the strings package.
• shortcut/shortcut.go
  • Introduced two new functions: 'ExtractShortcutStoryID' and 'GenerateShortcutStoryURL'.
• shortcut/shortcut_test.go
  • Included two test functions: 'TestExtractShortcutStoryID' and 'TestGenerateShortcutStoryURL'.
  • Used the 'assert' package from 'testify' for assertions in the tests.

Impact

These changes will allow users to generate Shortcut links more efficiently and customize their pull request descriptions. The new tests ensure that the new functions work as expected, increasing the reliability of the code. The changes also improve the readability and maintainability of the code by introducing a new structure and modifying the way information is generated and stored.

I don't think this related to shortcut, do you mind to create a new PR for that?

The structure doesn't look flexible and, in my opinion, needs improvement. What do you think about keeping the old flat logic without an extra structure and simply validating that only JIRA or shortcut are allowed? If both are passed, then return an error.
