search path is not change for the require command whn i configure the relative extension's paths

Nobody has claimed this yet.

### How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

### Which OS are you using?

Linux

### What is the issue affecting?

Libraries

### Expected Behaviour

I wrote the following code:
`local cjson = require 'posix.unistd'
print(type(cjson))
a = {}
print("aaaa")
from command line it is running perfectly
my LUA_PATH = `/usr/local/share/lua/5.4/?.lua;/usr/local/share/lua/5.4/?/init.lua;/usr/local/lib/lua/5.4/?.lua;/usr/local/lib/lua/5.4/?/init.lua;./?.lua;./?/init.lua
my LUA_CPATH = /usr/local/lib/lua/5.4/?.so;/usr/local/lib/lua/5.4/loadall.so;./?.so
LUA Runtime setting for the extension is as:
```
?.lua
?/init.lua
/usr/local/share/lua/5.4/?.lua;
/usr/local/share/lua/5.4/?/init.lua;
/usr/local/lib/lua/5.4/?.lua;
/usr/local/lib/lua/5.4/?/init.lua;
./?.lua;
./?/init.lua
```
LUA workspace library
/usr/local/lib/lua/5.4/?.so;
/usr/local/lib/lua/5.4/loadall.so;
./?.so
when i am running or debugging the program it still searches the workspace folder, any suggestion?

### Actual Behaviour

It should change the searching directory prior running to .so paths

### Reproduction steps

1. Go to '...'
2. code editor
3. write an include statement
4. Click '...'
5. run or debug
6. See error '...'
7. `module 'posix.unistd' not found:
no field package.preload['posix.unistd']
no file '/home/konstantinos/Desktop/server/lua-apps/posix/unistd.lua'
no file '/home/konstantinos/Desktop/server/lua-apps/posix/unistd.lua'
no file '/home/konstantinos/Desktop/server/lua-apps/posix/unistd.so'
no file '/home/konstantinos/Desktop/server/lua-apps/posix/unistd.so'
no file '/home/konstantinos/Desktop/server/lua-apps/posix.so'
no file '/home/konstantinos/Desktop/server/lua-apps/posix.so'`

### Additional Notes

error loading module 'posix.unistd' from file '/usr/local/bin/lua':
/usr/local/bin/lua:1: unexpected symbol near '<\127>'

### Log File

_No response_

Start by reproducing the LuaLS VS Code extension behavior on Linux with the reported LUA_PATH and LUA_CPATH values, then compare the configured paths with the paths used by require for posix.unistd. Done means the extension or runtime uses the configured shared-library paths instead of searching only the workspace folder.
