enh(scala) add inline soft keyword

[nicolasstucki]

Changes

Make inline a keyword when it is not part of a member selection of application.

Basic idea form https://github.com/scala/vscode-scala-syntax/blob/main/src/typescript/Scala.tmLanguage.ts#L665, but without the need to distinguish the two kinds of keyword.
Also see https://docs.scala-lang.org/scala3/reference/soft-modifier.html

Again, can't use look-behind. To solve "false positive" cases like this you can often introduce a second dummy rule like:

// consume inline as a property access
{ match: /\.inline/ } 

The dummy rule matches the property access case, preventing your highlighting rule from seeing that content.

Also, beginKeywords has this magic built-in but you'd need to be inside of a separate scope to take advantage of that, so I think my first suggestion may be what you want.

beginKeywords did not work with the `inline` + ... case.

Suggested change

	const INLINE_NAME_SELECT = {
	match: /\.inline\b/
	};
	const INLINE = {
	begin: /\binline(?=\s)/,
	keywords: 'inline'
	};
	// TODO: use negative look-behind in future
	const INLINE_MODES = [{
	match: /\.inline\b/
	},
	{
	begin: /\binline(?=\s)/,
	keywords: 'inline'
	}];

Lets keep them grouped I think.
