Annotations `@enum` and `@enum (key)` in JSON output

Personne n'a encore pris cette issue.

Annotations `@enum` and `@enum (key)` produce very different JSON output.

# Annotation `@enum`

```lua
---@enum level1
---Description of enum level1.
local level1 = {
low = 1, --Low level.
high = 2, --High level.
}
```
This enum creates the following JSON output:

```json
{
"defines": [
{
"file": "file:///home/andreas/Projects/Code/luals2dox/test/./enum/enum-02.lua",
"finish": 15,
"start": 9,
"type": "doc.enum"
}
],
"desc": "```lua\n{\n low: integer = 1,\n high: integer = 2,\n}\n```",
"fields": [],
"name": "level1",
"rawdesc": "```lua\n{\n low: integer = 1,\n high: integer = 2,\n}\n```",
"type": "type"
},
{
"defines": [
{
"file": "file:///home/andreas/Projects/Code/luals2dox/test/./enum/enum-02.lua",
"finish": 40007,
"start": 40003,
"type": "tablefield"
}
],
"desc": "High level.",
"fields": [],
"name": "level1.high",
"rawdesc": "High level.",
"type": "type"
},
{
"defines": [
{
"file": "file:///home/andreas/Projects/Code/luals2dox/test/./enum/enum-02.lua",
"finish": 30006,
"start": 30003,
"type": "tablefield"
}
],
"desc": "Low level.",
"fields": [],
"name": "level1.low",
"rawdesc": "Low level.",
"type": "type"
},
```

Issues:
- First block: `start` and `finish` numbers are wrong.
- Description of enum `Description of enum level1.` is missing.

Just curious:
- Why are there 3 separate blocks for this enum? I'd expected block 2 and 3 (enum items) to be sub-blocks of block 1 (enum). This would make it easier reading/postprocessing the JSON file.

# Annotation `@enum (key)`

```lua
---@enum (key) level2
---Description of enum level2.
local level2 = {
low = 1, --Low level.
high = 2, --High level.
}
```
This enum create the following JSON output:

```json
{
"defines": [
{
"file": "file:///home/andreas/Projects/Code/luals2dox/test/./enum/enum-02.lua",
"finish": 70021,
"start": 70015,
"type": "doc.enum"
}
],
"desc": "```lua\n\"low\" | \"high\"\n```",
"fields": [],
"name": "level2",
"rawdesc": "```lua\n\"low\" | \"high\"\n```",
"type": "type"
},
```

Issues:
- Description of enum `Description of enum level2.` is missing.
- Description of enum items `Low level.` and `High level.` are missing.

Reproduisez les deux exemples d'enum annotés de l'issue et examinez les points d'entrée du language server pour le traitement des annotations et la sortie JSON. Comparez les plages source et les descriptions propagées pour l'enum et ses éléments. C'est terminé lorsque les deux formes préservent les descriptions de l'enum et des éléments, signalent des valeurs de début/fin correctes et que la structure de sortie correspond au comportement prévu du projet.
