feat: add recover option to issue create command

Description

This MR introduces a -recover flag as discussed in #472 (closed). The intent is to save the glab issue create [OPTIONS] into a file if the creation fails. If the file exists, we try to load the contents into the issue options and attempt to create the issue again.

How has this been tested?

The easiest way to test locally is to force a failure before creating the issue with the API:

1. Return an error early in commands/issue/create/issue_create.go#L362:

   return errors.New("fail on purpose")

2. Build the binary with the deliberate error running make

3. Use a test project, I'm using https://gitlab.com/jaime/glab-cli-tests for my tests. Check it out locally and cd into the location

4. Once in the test location, use the glab binary that you built, e.g. /Users/jaime/dev/gitlab/cli/bin/glab

5. Attempt to create an issue using the -recover flag and verify it fails

   glab issue create -t "My issue" -d "Using recover function" --recover
   - Creating issue in jaime/glab-cli-tests
   Failed to create issue. Created recover file: /Users/jaime/.config/glab-cli/recover/jaime/glab-cli-tests/issue.json

6. Verify the file exists and contains the correct details

   cat /Users/jaime/.config/glab-cli/recover/jaime/glab-cli-tests/issue.json
   {"title":"My issue","description":"Using recover function","issue_link_type":"relates_to","milestone_flag":""}

7. Undo the first step by removing the error in commands/issue/create/issue_create.go#L362

8. Compile the binary again using make

9. Try to create the issue again with the -recover flag

   glab issue create -t "My issue" -d "Using recover function" --recover
   Recovered create options from file
   - Creating issue in jaime/glab-cli-tests
   #9 My issue (less than a minute ago)
   https://gitlab.com/jaime/glab-cli-tests/-/issues/9

10. Voila! Issue created and the recover file should have been removed

    cat /Users/jaime/.config/glab-cli/recover/jaime/glab-cli-tests/issue.json
    cat: /Users/jaime/.config/glab-cli/recover/jaime/glab-cli-tests/issue.json: No such file or directory
