LSP completions are case sensitive; add option to have them be case insensitive

[aral]

Summary

LSP completions are case sensitive at the moment. It would be nice to have the option to make them case insensitive.

Reproduction Steps

In the following example:

const FOO

console.log(fo)

pressing tab after fo results in:

(FOO is not shown.)

Why is this important?

Because it is more ergonomic not to have to press shift all the time.

Suggested implementation

Either:

1. Make case-insensitive auto-completion the default, or
2. Make case-insensitive auto-completion a setting (this could make use of the already existing smart-case setting)

Sorry, I can’t remove the bug label. This is an enhancement request, not a bug.

I'm curious how other editors do this. I assume this would be something the language server would handle itself when figuring out what completions are available, but maybe we can handle it on the client side by figuring out permutations of the text for snake-case, camel-case, shout-case, etc.

@the-mikedavis Not sure. I’m currently using the TypeScript LSP (https://github.com/typescript-language-server/typescript-language-server).

I know that in VSCode the completions are case insensitive (at least by default, I never felt the need to change that).

I'm coding in typescript now and suffering from this, where should I look to even try to improve this.
