feat(version): configurable pr-body

[furcan]

Context

There are some open discussions around it but no outcome or decisions.

Changesets as developer-intent release management tool can be used/in-use broader then only NPM Packages.
if package.json present, and SemVer is a preferred version management for any project, this tool (from CLI to Action) can be used.

The current PR description with pre-state, max content length etc explicitly targeting NPM and Publishing to an NPM artifactory types of wordings.

Changes

What this PR does is

• respecting entire logic as is, not creates any regression
• introducing an optional pr-body input, as following the same naming convention that is picked since v2.
• allowing consumers to use {PACKAGES_INFO} special identifier in anywhere they want to use in their custom PR body text. THIS_AND_THAT \n{PACKAGES_INFO} or just WHATEVER

Additional Code Changes

I can revert these if owners/maintainers don't likes

• isObject util moved from run.ts to utils.ts, extended with array check
• isString util added for new prBody to allow explicitly only string when runtime
• non-executable code(types) moved to run.types.ts file for the touched functions => getVersionPrBody + runVersion
  • to keep the file simple and readable and by the intent, its runtime code, not build time.

Whats remaining

• Get review from owners
• Document this addition on READMEs and related workflows inputs(if any)
• add a changesets entry as minor for this action
