[GSK-1069] Add text transform: remove accents

[ghost]

Description

I implemented TextAccentRemovalTransformation to remove accents with a perturbation rate that defaults to 1.0 (to remove all accents).

Note

For the test, I used the texts and expected results from the issue (#1741).
Let me know if you want me to use the rate to ensure it is working appropriately.

Looks good, thanks! I would just add an extra example in the test.
