"array-like" table can't be natively annotated as enum

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?

Annotations, Hover

### Expected Behaviour

On hover over `action` param in my function I'd like to get annotation consistent with already existing annotation that i get if i hover over `all` in `actions.all` :
```
(field) actions.all: {
[10]: string = "supportAttack",
[11]: string = "supportDefence",
[12]: string = "supportBoth",
[13]: string = "supportAttackPike",
[14]: string = "supportDefencePike",
[15]: string = "stanceShieldwall",
[16]: string = "stanceLastman",
[17]: string = "stanceBarrage",
[18]: string = "encamp",
[19]: string = "uncamp",
[1]: string = "retreat",
[20]: string = "destroyCamp",
[21]: string = "buildFort",
[22]: string = "demountFort",
[23]: string = "destroyFort",
[24]: string = "rest",
[25]: string = "respire",
[2]: string = "move",
[3]: string = "swap",
[4]: string = "forcedMove",
[5]: string = "melee",
[6]: string = "shoot",
[7]: string = "shoot2",
[8]: string = "breakthrough",
[9]: string = "enclosing",
}
```
Essentially i'd like enum for this array to give the same behavioir as alias like this
```lua
---@alias Action
---| '"retreat"'
---| '"move"
---| '"swap"'
---| '"forcedMove"'
---| '"melee"'
---| '"shoot"'
---| '"shoot2"'
---| '"breakthrough"
---| '"enclosing"'
---| '"supportAttack"'
---| '"supportDefence"'
---| '"supportBoth"'
---| '"supportAttackPike"'
---| '"supportDefencePike"'
---| '"stanceShieldwall"'
---| '"stanceLastman"'
---| '"stanceBarrage"'
---| '"encamp"'
---| '"uncamp"'
---| '"destroyCamp"'
---| '"buildFort"'
---| '"demountFort"'
---| '"destroyFort"'
---| '"rest"'
---| '"respire"'
```

### Actual Behaviour

On hover over `action` param in my function I get this annotation:
```
(parameter) action: Action
{
}
```

### Reproduction steps

Consider this minimal code snippet:
```lua
local actions = {}

---@enum Action
actions.all = {
"retreat",
"move",
"swap",
"forcedMove",
"melee",
"shoot",
"shoot2",
"breakthrough",
"enclosing",
"supportAttack",
"supportDefence",
"supportBoth",
"supportAttackPike",
"supportDefencePike",
"stanceShieldwall",
"stanceLastman",
"stanceBarrage",
"encamp",
"uncamp",
"destroyCamp",
"buildFort",
"demountFort",
"destroyFort",
"rest",
"respire",
}

actions.isStance = {stanceShieldwall = true, stanceLastman = true, stanceBarrage = true}

--- @param action Action
--- @return boolean
function actions.IsStance(action)
return actions.isStance[action]
end
```

### Log File

_No response_

Start with the minimal Lua reproduction in the issue and trace how the @enum annotation on actions.all and the Action parameter are represented for hover. Compare that path with the existing alias behavior. Done means hovering the action parameter exposes the enum's string members consistently with the actions.all hover result.
