Fix broken links in documentation

Add all Microsoft Store releases to the IDE version blocklist

For the second time, the script has been broken by a tag used for a release specific to the Microsoft Store version of the Arduino IDE. Both times this happened, the tag has followed a consistent format. So I have generalized the regular expression to exclude all such tags in hopes this will prevent any future occurrences of this issue.

Blacklist the 1.8.11-ms-store-11 tag

This version is not available for download.

Ignore a ShellCheck SC2206

Quoting as they suggest breaks the script. I couldn't figure out another solution so I gave up and told ShellCheck to ignore it for now.

check_folder_name: Don't say "ERROR" in the output

check_library_properties uses check_folder_name, but only to display warnings. Thus, the use of "ERROR" in the check_folder_name output resulted in incorrect output from check_library_properties.

Add blank library.properties url field check to check_library_manager…

Documentation: Add table of contents

Fail build if build_sketch passed invalid IDE version

Previously the build_sketch command would return 0 if IDE version(s) that aren't installed were specified.

Make the duplicate IDE version code not mess up sort order

The list was originally sorted correctly by version but it appears the sort --unique command changes the sort order back to alphabetical.

Test files in this repository for correct formatting during CI build

Build fails from:
- Trailing whitespace
- True tabs
- No newline at end of file
