Migrate remaining text based scope types to new scope handler setup

[pokey]

We'd like to migrate all of our scope types to use the new scope handler setup introduced in #1031. See

• existing scope handlers such as TokenScopeHandler,
• the ScopeHandler interface definition, and
• the NestedScopeHandler class, which might be of use

Scope types to migrate

• Migrate notebookCell to use a scope handler #1053
• Migrate document to use a scope handler #1054
• Migrate paragraph to use a scope handler #1055
• Migrate nonWhitespaceSequence to use a scope handler #1056
• Migrate boundedNonWhitespaceSequence to use a scope handler #1057
• Migrate url to use a scope handler #1058
• Migrate collectionItem to use a scope handler #1059
• Migrate customRegex to use a scope handler #1060
• Migrate surroundingPair to use a scope handler #1061

I'm looking into migrating the notebook cell scope and just realize that we are actually using notebookCell in markdown.

cursorless/queries/markdown.scm

Lines 54 to 63 in 8cd7c21

	(
	(fenced_code_block
	(fenced_code_block_delimiter) @_.interior.start.endOf
	.
	(block_continuation)
	(fenced_code_block_delimiter) @_.interior.end.startOf
	) @notebookCell
	(#trim-end! @notebookCell)
	(#insertion-delimiter! @notebookCell "\n\n")
	)

The problem of course is that you can have markdown cells in a python notebook. What would "take next cell" do in a markdown cell?

[pokey]

I think that should just function like a nested scope, no? Haven't thought much about implementation but I think desired behaviour is well defined. Ie if you're in a code block in a markdown cell, then it targets next code block in the same cell if it exists, otherwise next cell. I believe that's how a nested scope would behave

[AndreasArvidsson]

But what if you are not in a code block in markdown? Should next cell refer to a markdown code block further down or a next notebook cell?

Implementation wise I think it simplest to just ask the language scope provider and if we get no results go for a notebook cell. Does that sound good?

[pokey]

I think the consistent thing to do if we're treating it as nested scope would be to go to next markdown code block if we find one in current cell, otherwise next cell

Tho I do think that might be surprising, which kinda argues they should really be different scopes

[AndreasArvidsson]

I think we will get that behavior if we do as I specified above.

But a different scope for notebook cells is of course another option. Maybe we should start with a combined one and see if anyone runs into problem?

All of these are done.
