Fix double-slash paths in .tx/config file_filter entries

[coderabbitai]

Description

Multiple entries in the .tx/config file contain double slashes in their file_filter paths (e.g., locale//<lang>/LC_MESSAGES/... instead of locale/<lang>/LC_MESSAGES/...).

According to Transifex documentation, file_filter patterns should use single slashes between path components. Double slashes are not documented as valid syntax and can create empty path segments that may break file matching during push/pull operations.

Affected Lines

The issue affects numerous entries throughout the file, including but not limited to lines: 45, 54, 63, 102, 112, 122, 132, 142, 152, 162, 172, 182, 192, 202, 212, 222, and many others.

Context

This issue was identified during review of PR #540 but is pre-existing (not introduced by that PR).

It's unclear if this is actually a problem since translation data appears to be working
