feat: java-debug-adapter, java-test

[lvimuser]

closes #433

I've opted for using the prebuilt files extracted from .vsix because maven takes a while to build.

Not sure if we should link java-test or not, since it's more like a 'lib' than an executable (should it still be in the DAP category?).

usage with nvim-jdtls#java-debug / nvim-jdtls#vscode-java-test:

local function get_install_path(package_name)
  return require("mason-registry").get_package(package_name):get_install_path()
end

local bundles = {
  vim.fn.glob(
    -- or
    -- get_install_path("java-debug-adapter") .. "extension/server/com.microsoft.java.debug.plugin-*",
    vim.fn.stdpath "data"
      .. "/mason/packages/java-debug-adapter/extension/server/com.microsoft.java.debug.plugin-*.jar",
    true
  ),
}

vim.list_extend(
  bundles,
  vim.split(
    vim.fn.glob(
      -- or
      -- get_install_path("java-test") .. "extension/server/*.jar",
      vim.fn.stdpath "data" .. "/mason/packages/java-test/extension/server/*.jar",
      true
    ),
    "\n"
  )
  
-- if not filtered, raises the following error
--[[
  Failed to load extension bundles
  Failed to get bundleInfo for bundle from com.microsoft.java.test.runner-jar-with-dependencies.jar
]]
bundles = vim.tbl_filter(function(s)
  return not vim.endswith(s, "com.microsoft.java.test.runner-jar-with-dependencies.jar")
end, bundles) or {}

Coo! few comments

Great! I added some to the description of java-test (removed specific mention of nvim-jdtls). I also removed the _.gsub("^v", "") as it's not needed

Thanks!
