[[ and ]] go to beginning and end of file, not by "section"

Describe the bug
I'm trying to navigating within a typescript file using the [[ and ]] commands, that are supposed to move by "section". I'm not clear exactly what a section is but in Zed it moves by a chunk of code, like one function to another. According to Neovim docs a section has some kind of relation to { symbols. But in VS Code, [[ and ]] move to the beginning and end of the TypeScript file, and the number I put at the beginning seems to have no effect.

To Reproduce
Open up any large typescript file. Put the cursor in the middle of a chunk of code. Press [[ or ]].

Expected behavior
Moves by some reasonable chunk of code, like function to function or statement to statement. I'm not familiar enough with VIM and Neovim to know exactly what it should do.

Environment (please complete the following information):

• Extension (VsCodeVim) version: 1.29.0
• VSCode version: 1.96.0
• OS: MacOS

Additional context
None

Reproduce the behavior in a large TypeScript file using the [[ and ]] commands, as described, with the reported VSCodeVim and VS Code versions. Then locate the command handling and any related tests; done should mean the commands move through meaningful sections with counts affecting the result, according to the project's defined semantics.
