Correction suggestion to link used for the dataset

[jmos-cruz]

Hello @fabianoluzbr,

Great work with the model!

Just want to add something in regards to the README.md file. Unfortunately, sometimes official websites from Portugal do not have the greatest user experience, with important links being hidden from sight. portaldalinguaportuguesa.org is such a case, especially in regards to the dataset that you used, which was really hard to find. I am linking it here in case someone in the future is trying to find it: http://www.portaldalinguaportuguesa.org/index.php?action=fonetica&act=list&region=spx&search=

Thank you!

PS: You are free to close the issue, if you wish.
