bisync: release from beta

As of v1.71, bisync is officially out of beta.

Some history:

- bisync was born in 2018 as https://github.com/cjnaz/rclonesync-V2
by @cjnaz, written in python.
- In 2021, @ivandeex ported it to go with @cjnaz's support.
https://github.com/rclone/rclone/pull/5164
- It was introduced as an "experimental" feature in v1.58.
6210e22ab5
- In 2023, bisync needed a new maintainer, and @nielash volunteered.
https://forum.rclone.org/t/bisync-bugs-and-feature-requests/37636
- Later in 2023, bisync received a major overhaul and was relabeled "beta"
(from "experimental"). https://github.com/rclone/rclone/pull/7410
- In 2024, integration tests were introduced for bisync (which previously had
only unit tests). https://github.com/rclone/rclone/pull/7693
- As of August 2025, bisync is stable and integration tests are passing on all
of the "flagship" backends.

Development doesn't stop here, of course. But bisync has come a long way since
its "experimental" days, and the "beta" tag is no longer needed.

 ### Supported backends

+Bisync is integration-tested against all rclone backends to verify compatibility.
+Most backends (including all backends not listed below) are deemed fully
+supported with no known issues. Occasionally, however, these tests reveal issues
+with particular backends, usually related to a provider-specific limitation
+beyond rclone's control (for example, disallowed special characters and filename
+encodings.)

-- Google Drive
-- Dropbox
-- OneDrive
-- S3
-- SFTP
-- Yandex Disk

 modification times, and refused to run otherwise.
 This limitation has been lifted as of `v1.66`, as bisync now supports comparing
 checksum and/or size instead of (or in addition to) modtime.
