(Chore) Add -f flag to clear_build.sh script delete static folder

[vbaranov]

Motivation

Add the ability to delete a folder with static assets before the launching of another Blockscocut instance.

Changelog

Enhancements

• -f flag has been added to clear_build.sh script to be able to also delete ./priv/static/ folder before the launching of another Blosckout instance

  • I added an entry to CHANGELOG.md with this PR
  • If I added new functionality, I added tests covering it.
  • If I fixed a bug, I added a regression test to prevent the bug from silently reappearing again.
  • I checked whether I should update the docs and did so if necessary

Shouldn’t it be -f or —force? Doesn’t really matter though.

Thanks @zachdaniel. You are completely right. Changed to -f.
