Write a function `find_adverb_position` that takes a string `text` as input and returns a tuple containing the start position, end position, and the adverb itself for the first adverb found in the text. An adverb is defined as a word ending with "ly". If no adverb is found, return `None`.
#### Example Usage
```python [main.nopy]
find_adverb_position("clearly!! we can see the sky")
# Output: (0, 7, 'clearly')
find_adverb_position("seriously!! there are many roses")
# Output: (0, 9, 'seriously')
find_adverb_position("no adverbs here")
# Output: None
```
