Root directory content refactoring (#1725)

* Root directory refactoring: - move info about Bootup Logo from a sepatate README to main README; - replace separate root scripts build.sh and start_dev.sh by root Makefile; - make Scripts directory and move there: flash_ts100_linux.sh script, ci/ directory, dockerfile, LICENSE_RELEASE, and PULL_REQUEST_TEMPLATE; - reconfigure build & deploy scripts according to changes

* Scripts => scripts

* Scripts -> scripts: re-add missing renamed files

* Directories refactoring: add top-level Makefile, add scripts/deploy.sh script, move github templates from top-level dir to .github, organize files inside Development Resources

* Update scripts/deploy.sh accroding to codestyle syntax shellcheck

* Makefile: add docs-deploy target for mkdocs gh-deploy

* Rename IronOS.yml > Env.yml, update related files

* Docs configs: remove empty characters

* docs/devel: update usage of new script

scripts/deploy.sh
