feat: allow compilation of post-upgrade commands

[IKatsuba]

Changes:

This PR adds compilation as templates for post-upgrade commands.

Context:

I would like to configure Angular migrations for some npm packages. For this feature, I have to know about the previous and current package versions in post-upgrade commands. But it is possible only if commands will compile as templates in the changing context. For example

{
  "postUpgradeTasks": {
    "commands": [
      "npm ci --ignore-scripts",
      "npx ng update {{{depName}}} --from={{{fromVersion}}} --to={{{toVersion}}} --migrateOnly --allowDirty --force"
    ],
    "fileFilters": ["**/**"]
  }
}
