Parse Tree view doesn't update parse/lex rule names when they change

[chris-miner]

I did the following:

1. created a simple grammar with one parse rule, and one lexer rule
2. created a sample data file
3. launched the "Debug ANTLR4 grammar" item referencing the grammar and data file
4. the system produced a lovely parse tree complete with labels for the rules represented
5. changed a name of a rule
6. repeated step 3

Found: The lovely parse tree labels are not updated to reflect the new rule names

Workaround: If you collapse the part of the tree with the as yet not updated label, and then re-expand it, the labels update.

This issue still exists today in the latest version, but now it requires opening and re-starting VSCode to get the labels to update. Is there any insight into why this is happening and when/if it will be fixed?

Fixed in release 2.4.0
