More work with broken links

[NexiusTailer]

The previous PR which was full about link fixes was probably the hugest one from me here, so I was sure that most of the issues with both internal and external broken links are solved today, but then I scanned it again with some automated tools and found something again:

1. Fixed remaining incorrect paths in links to other docs sections. For example, there were still some cases when linking a callback in native function article was made without ../callbacks/ part, etc

2. Fixed remaining absolute links and made them relative, so users won't be accidentally kicked to English pages (or even to 404 if the path were from previous pre-docusaurus era) when they read translations and jump between articles

3. Images which link to external resources were checked and corrected where it was necessary

4. Corrected many invalid links to #anchors. Also, sa-mp.cfg links now point to the dedicated sa-mp.cfg page, as most translations of ClientCommands page lack the "File sa-mp.cfg" section

5. Point deprecated functions (mentioned on changelog page) without their own article to the existing one:
   GetObjectTarget -> GetObjectMovingTargetPos
GetPlayerObjectTarget -> GetPlayerObjectMovingTargetPos
SendRconCommandf -> SendRconCommand (and other similar functions of this kind)
   GetPlayerCameraTargetPlayerObj -> GetPlayerCameraTargetPlayerObject
GetPlayer3DTextLabelVirtualW -> GetPlayer3DTextLabelVirtualWorld
SetPlayer3DTextLabelDrawDist -> SetPlayer3DTextLabelDrawDistance

6. Corrected newly found mistakes and typos in links like:
   OnFilterSciptExit -> OnFilterScriptExit
OnPlayerGiveDamags -> OnPlayerGiveDamage
OnPlayerDisonnect -> OnPlayerDisconnect
PlayerTextDrawCreate -> CreatePlayerTextDraw
GetPlayerVerion -> GetPlayerVersion
ResetPlayerWeapon -> ResetPlayerWeapons
GetPlayerCaemraFrontVector -> GetPlayerCameraFrontVector
GetPlayerCameraAspectRation -> GetPlayerCameraAspectRation
NPC_(Get/Set)SurfingOffset -> NPC_(Get/Set)SurfingOffsets
CommonIssues -> CommonClientIssues
b_close -> db_close

7. Fixed newly found markdown link patterns with typos: [text] (url) with a stray space, [text]url) missing paren, etc

8. Removed some (much probably) poor AI generated links to non-existent natives in zh-CN:
   IsPlayerEditingAttachedObject, RemoveBuildingForPlayerEx, SetVehicleTrainSpeed, ResetVehicleOccupiedStatus, GetGameModeText, floatfloor and floatceil

and the same kind of slop in NPC docs including in all translations:
NPC_SetPosition, NPC_GiveWeapon, NPC_RemoveWeapon, NPC_Reload and NPC_StopShoot
