We should automatically escape single quotes when pasting into a string

Related to #9509
Easy to add from #9996

E.g. you have this:
```bicep
@description('')
param resourceId string
```
and you want to copy this description into the description string:
```
This represents a resource's ID
```

Currently you get this (with an error):
```bicep
@description('This represents a resource's ID')
param resourceId string
```

EXPECTED:
```bicep
@description('This represents a resource\'s ID')
param resourceId string
```

Read related issues #9509 and #9996 first, then reproduce the pasted description example to locate the paste-handling entry point. Done means a single quote pasted inside the Bicep single-quoted string is escaped and the resulting template no longer produces an error.
