Fix tool arguments formatting in StructuredChatAgent (#10480)
In the `FORMAT_INSTRUCTIONS` template, 4 curly braces (escaping) are
used to get single curly brace after formatting:

```
"{{{ ... }}}}" -> format_instructions.format() ->  "{{ ... }}" -> template.format() -> "{ ... }".
```

Tool's `args_schema` string contains single braces `{ ... }`, and is
also transformed to `{{{{ ... }}}}` form. But this is not really correct
since there is only one `format()` call:

```
"{{{{ ... }}}}" -> template.format() -> "{{ ... }}".
```

As a result we get double curly braces in the prompt:
````
Respond to the human as helpfully and accurately as possible. You have access to the following tools:

foo: Test tool FOO, args: {{'tool_input': {{'type': 'string'}}}}    # <--- !!!
...
Provide only ONE action per $JSON_BLOB, as shown:

```
{
  "action": $TOOL_NAME,
  "action_input": $INPUT
}
```
````

This PR fixes curly braces escaping in the `args_schema` to have single
braces in the final prompt:
````
Respond to the human as helpfully and accurately as possible. You have access to the following tools:

foo: Test tool FOO, args: {'tool_input': {'type': 'string'}}    # <--- !!!
...
Provide only ONE action per $JSON_BLOB, as shown:

```
{
  "action": $TOOL_NAME,
  "action_input": $INPUT
}
```
````
