Issue:
Providing filename instead of txt to TextClip results in filename being written instead of the actual content of the file
#### Expected Behavior
Providing a filename to TextClip instead of txt parameter should produce an image with the text in the provided file being set on the image, for example the following two snippets should produce the same output:
```python
text_clip = TextClip(
    filename=temp.txt,
    font="Roboto-Bold",
    size=(300, 135),
    color="#4390C8",
    bg_color="#323232",
    method="caption",
    remove_temp=False,
    print_cmd=True,
)
```

```python
text_clip = TextClip(
    txt="Hello",
    font="Roboto-Bold",
    size=(300, 135),
    color="#4390C8",
    bg_color="#323232",
    method="caption",
    remove_temp=False,
    print_cmd=True,
)
```
Where file temp.txt contains *Hello* in it.
Both snippets should produce an image like this one:
![tmpsrd22otw](https://user-images.githubusercontent.com/19710525/171849838-989b294d-dc64-42b8-a1c3-1d32c95e6d3f.png)

#### Actual Behavior
The first one produces the following image:
![tmpam1o1mzg](https://user-images.githubusercontent.com/19710525/171849595-16942cc9-e333-4a87-8745-3e3f63c16e0e.png)
Where the second one produces the following image:
![tmpsrd22otw](https://user-images.githubusercontent.com/19710525/171849838-989b294d-dc64-42b8-a1c3-1d32c95e6d3f.png)


#### Steps to Reproduce the Problem
<!-- Please include code that demonstrates this problem so that we can reproduce it. For advice on how to do this, see https://stackoverflow.com/help/mcve -->
Run the above snippets after importing from editor
```python
from moviepy.editor import *
```
and check the temp file generated, it will be printed

#### Specifications

  - Python Version: 3.8.10 (default, Mar 15 2022, 12:22:08) \n[GCC 9.4.0]
  - Moviepy Version: 1.0.3
  - Platform Name: Ubuntu
  - Platform Version: 20.04.4 LTS 64bit

#### Solution
LIne: moviepy/video/VideoClip.py:1101
is responsible of this bug, just deleting the `%` in parameter value will fix the problem, tested on multiple files, and also you can sse this is the correct way by looking at line: 1098 and also to check imagemagick [docs](https://imagemagick.org/Usage/text/#caption_paragraphs)
