Provide multiple quick fix options with substitution rule

[goerks]

Given the following rule

extends: substitution
message: Use '%s' instead of '%s'
level: error
ignorecase: true
action:
  name: replace
swap:
  whatif: what if|options|more

When hover over text whatif

Then I expect the substitutions are what if, options and more 🆗
And I expect a list with these quick fixes what if, options and more ⛔

Current behavior

• The first substitution string is contained twice

Expected behavior

• Three quick fixes are shown in this order
  1. what if
  2. options
  3. more

Environment

• Windows 10
• VSCode 1.79.2
• Vale VSCode v0.17.3
