Expected Behaviour

I would like to get the current version for lua-language-server without changelog.md file.

Improve Lua code in script/version.lua to get current version (last Git tag).

Actual Behaviour

When a contributor packages lua-language-server for a distribution (Linux or BSD), the changelog.md file is not always included.

In script/version.lua file, the current version is defined (function loadVersion) with parsing of the changelog.md file. If this file is not present, the returned version is Unknown.

It will be better to get the current version without parsing of changelog.md file => get version from the last Git tag or define the current version in script/version.lua file.

從 script/version.lua 中的 loadVersion 開始，檢查目前版本是如何從 changelog.md 推導出來的。重現缺少 changelog.md 的打包情境，然後驗證版本來自最後一個 Git 標籤或明確定義的值，而不是回傳 Unknown。
