Adjust default settings to F# code formatting guidelines

[alfonsogarciacaro]

Three of the default settings doesn't seem to match the F# code formatting guidelines. Maybe they should be changed?

• noSpaceAfterComma -> should be false
• noSpaceAfterSemiColon -> should be false
• noSpaceAroundDelimiter -> should be false

It seems the VS Code extension is using fantomas CLI arguments (with a no in front) but the defaults from the API so the effect is the opposite.

Another solution could be to remove the no prefix (and adjust the behaviour accordingly). This may be more clear for users.

Thank you! I embraced your suggestion to remove the no prefix.
