feat(ts_ls)!: rename `tsserver` to `ts_ls` #3232

`tsserver` cannot be used as an abbreviation for `typescript-language-server`, because there is [`tsserver`](https://github.com/microsoft/TypeScript/wiki/Standalone-Server-(tsserver)) already and it is completely different from `typescript-language-server`. This is misleading.

As the [README of `typescript-language-server`](https://github.com/typescript-language-server/typescript-language-server/blob/master/README.md) says, it's a wrapper of `tsserver`. This abuse has been around for so many time in lspconfig that people don't realize they are two different things, and are then confused by replacements of `typescript-language-server` like [typescript-tools.nvim](https://github.com/pmizio/typescript-tools.nvim) and [vtsls](https://github.com/yioneko/vtsls).
