Update the URL to matrix-appservice-discord

The URL seems to have been changed at least since several years though the exact date is unknown to me, considering the latest tagged docker image on https://hub.docker.com/r/halfshot/matrix-appservice-discord/tags (https://hub.docker.com/layers/halfshot/matrix-appservice-discord/develop/images/sha256-a1015907545603448d2d8e2ea0d31f0fdb6c7676009e2cb38e324440a9284317) is dated Feb 15, 2021.

Replace existing links to matrix-org/synapse which should be replaced

Note that links to the issues and PRs on the original repository (matrix-org/synapse) should not be replaced with ones on the forked one (element-hq/synapse) as those are not available on the latter, where the issues and PRs with the same number as matrix-org/synapse are "reserved" to avoid conflicts between those repositories. For reasoning of such complexity (including the reason why trasferring the original repository to element-hq/synapse was avoided), see: https://github.com/element-hq/synapse/issues/6#issuecomment-1861116896

Consistent usage of the words related to BorgBackup (Borg)

In order to avoid confusions between the name of the program itself (BorgBackup and Borg in short) and the backups managed by BorgBackup, the official full name should be preferred where possible, minding capitalization.

- Borg or borg → BorgBackup
- Borg backup(s) → BorgBackup (if it means the program) / backups with BorgBackup (if it means the backups managed by the program)

Based on https://www.borgbackup.org/

Fix capitalization: Dimension Integration Manager → Dimension integration manager

Based on https://github.com/turt2live/matrix-dimension
> An open source integration manager for matrix clients, like Element.

"Dimension" is one of the integration managers, and it is not something like Dimension Integration Manager, which could be abbreviated as DIM.

Also:
- Replace "integrations manager" with "integration manager"
- Fix typos
- Remove a line break
