Fix typo in MDX documentation

[ManuLpz4]

I was reading the documentation related to MDX and noticed a typo in some articles, so I fixed them.

Although I read the Contribution Guidelines this is my first contribution so feel free to comment if I can do better.

I believe the article (a or an) in this case refers to the word file, so a file (the current way) should be correct

Hey, @Netail! Thank you for helping me on my first PR. I'm looking for official recommendations on it and I only found that the preceding word is the part the defines if it should be an a or an an.

Do you have some article talking about the principle noun? I'm not a native speaker so maybe it is something that is not written but commonly used :)

@Netail Thank you for helping out! As we are going to read as an MDX components dot tsx file, I also agree that it can be written with an.
