A brand new Release Notes feature for Releases being made by 'build.cake' script

[raman-m]

New Feature

• Release Notes looks more user friendly to have a fun 😄
• Upgrade build.cake script

This is preparation PR for upcoming release 19.1.x or a brand new 20.0.0 one. So, after delivering script upgrade to develop branch, a new release branch release/20.0.0 will be created.

Proposed Changes

• Release Notes file aka ReleaseNotes.md was renamed and content now can contain a header templates for Release Notes. Now placeholder {0} is used to substitute current SemVer version (release version) to the release name in the header
• The ReleaseNotes.md file processing has changed.
  Old process: 1) Read all commits from Git → 2) Transform to notes item with hash, author, feature/commit message; → 3) Flush string stream to ReleaseNotes.md for NuGet packaging → 4) finally calling Version task and ignoring SemVer.
  New process: 1) Run Version task first → 2) Paste SemVer value into Release Notes placeholders → 3) Generate new Notes style 3) Flush string stream to ReleaseNotes.md for NuGet packaging → 4) finally not calling Version task, but reusing SemVer where applicable.
• Refactor the CreateReleaseNotes task completely defining new local helper functions: introduce new generator for new Notes style, use more git statistics on features delivered, create Top 3 contributors, describe release influencers, get more info on features delivered
• Refactor some tasks to remove ugly warnings from building log
• Change tasks dependencies: create release notes in Release task only (not calling for Version or Compile tasks, no sense). That means all PR builds will not generate Release notes calling CreateReleaseNotes task. So, there is no sense to generate ReleaseNotes.md file for PRs. And, only Release mode on CircleCI during making a Release build for main branch will call this task. So, we will have a little bit faster PR builds. Currently we save 10-20 milliseconds 🤣
• Add DONE status for each task after completion. Better to check the name of finished task, and watch for process chain (tasks dependencies). This can be enhanced in future.
• Add reference to Spectre.Console package to use fantastic AnsiConsole helper for logging with colored messages
