Can't make .htaccess editable from manager in 3.0

[Mark-H]

Bug report

Summary

In 2.x, adding htaccess to the upload_files system setting would allow you to edit .htaccess files from the manager. That doesn't seem to work in 3.0.1 anymore.

Step to reproduce

Add htaccess to the upload_files system setting.

Observed behavior

Error File extension `` is not permitted.

Expected behavior

Allow editing .htaccess files when opted in.

Environment

Probably all.

The problem seems to be this line in the sanitize function that removes the dot from the file name. https://github.com/modxcms/revolution/blob/26866e13963084610bb03c89b635654813f55a86/core/src/Revolution/Processors/Browser/Browser.php#L146

Maybe that can be restricted to two starting dots: #^(\.{2}|/)+#u

Should be safe: https://regex101.com/r/FbuRLQ/1

The dot files have to be restricted elsewhere.

That's also how it's done in 2.x: https://github.com/modxcms/revolution/commit/74044ab4fcadb4ad65b9cc5e485e1a2ee737b2c4
