Documentation: Migration guide to PrimeNG v18 doesn't include "InputTextarea" to "Textarea"

[peach-v33]

Describe the bug

The version 18 migration guide does not include that "InputTextarea" and "InputTextareaModule" are no longer available, and were replaced by "Textarea" and "TextareaModule". Probably should be in the "Removed Components" section with a note that Textarea can be used instead, but the old version is removed not deprecated.

Version 17: https://v17.primeng.org/inputtextarea

Version 18 (and 19): https://v18.primeng.org/textarea (https://primeng.org/textarea)

Reason for not contributing a PR

• Lack of time
• Unsure how to implement the fix/feature
• Difficulty understanding the codebase
• Other

Other Reason

On the clock at work. Would have to contribute in my personal time (may do that in future, but for now, logging the bug).

Reproducer

not relevant. It's documentation.

Environment

Issue is on the documentation on the main primeng site, not my environment.

Angular version

19.1.1

PrimeNG version

v19

Node version

20.18.0

Browser(s)

Chrome.

Steps to reproduce the behavior

1. Go to the v18 Migration guide: https://primeng.org/guides/migration
2. Look at the list of deprecated and removed components. InputTextarea isn't there.

Expected behavior

InputTextarea should be mentioned with appropriate instructions for migrating to Textarea.

It should also be noted that the directive pInputTextarea is renamed to pTextarea.

Unfortunately angular is not throwing an error when pInputTextarea is used. So you have to do a global search and replace.
