feat: Support for commonly used words/acronyms along with the base dictionary

[OXY2DEV]

The problem

_{1200+ diagnostics from Harper in a markdown file}

Currently the plugin only supports words of the dictionary. This unfortunately leads to a lot of false positives when using this LSP on specific types of files.

For example,

In lua, when using luaCATS this causes issues when using these annotations.

---@param
---@nodiscard
---@vararg

As quite a few repositories use release-please to generate a CHANGELOG.md file. The files title is CHANGELOG.

Unfortunately, this gets picked up by this LSP as an incorrect spelling. I think the LSP should ignore it.

This also introduces a new issue as commit messages usually look something like this.

feat(renderer): Added support for custom renderer

This also gets picked up by the LSP. This can lead to a LOT of false positives. I have almost 1200+ in 1000 line file.

It would be nice if the LSP could understand words used in editors(in my case Neovim).

For example,

extmark
autocmd
augroup

But this can be ignored.

---

As the scope of this is WAY TOO big(as the LSP by default activates in quite a few filetypes) this can either be solved by,

1. PRs(most likely from users) adding dictonaries for specific languages.

2. Adding pattern(s) that the LSP would ignore.

But you should decide what will be the best solution.
