feat(rails): support multi-database aliases (#13368)

Browse Source 
Rails applications can define more than one database (`primary`, `cache`, `cable`, `queue`, ...), and each one gets its own namespaced task. These commands accept an optional database name as the first argument:

`rdc`, `rdd`, `rdm`, `rdmd`, `rdmr`, `rdms`, `rdmu`, `rdr`, `rdrs`, `rdsl`

### Multiple databases
Rails applications can define more than one database (`primary`, `cache`, `cable`,
`queue`, ...), and each one gets its own namespaced task. These commands accept an
optional database name as the first argument:
`rdc`, `rdd`, `rdm`, `rdmd`, `rdmr`, `rdms`, `rdmu`, `rdr`, `rdrs`, `rdsl`
```zsh
rdm # rails db:migrate
rdm cache # rails db:migrate:cache
rdm VERSION=20231225 # rails db:migrate VERSION=20231225
rdm cache STEP=2 # rails db:migrate:cache STEP=2
rdm --trace # rails db:migrate --trace
```
The first argument is read as a database name only when it is a bare word. Flags
(`--trace`), variables (`STEP=2`) and other tasks (`db:seed`) are passed through to
`rails` unchanged, so previous usage keeps working. When a database name is given,
the resolved command is printed so it is clear which database is being used.
`rdmrs` is not in the list above because Rails does not define a per-database
`db:migrate:reset` task.
Note that these are implemented as shell functions rather than aliases, so they will
not appear in the output of `alias`.
