This adds tests, supported types, and a signature image for `to_string`
and `to_version`. It also fixes the resolution of functions who's names
contain an `_`
Finally, it updates the docs for `ceil` to render the image more nicely.
Add the 'right' function, which extracts a substring beginning from its
right end (opposite function of 'left').

CI will skip building them. Lot's of CI machines don't have font support
so they can't generate these. But all local machine have a GUI so they
can.
Also, super-lazy initialize the font so CI don't bump into it by
accident.
Closes#99018
Add the unary scalar function CEIL.
Analogously to FLOOR, it rounds up its argument.
- Implement CEIL, add it to the function registry and make sure it is serializable.
- Add csv tests, unit tests and docs.
- Add additional csv tests with different data types and some edge cases for both CEIL and FLOOR
- Add unit tests and update docs for FLOOR.
Locks the railroad diagrams to always use the same font, this one named
`roboto mono`. This makes sure that when we render the railroad diagrams
we always size them the same way. Because everyone has a copy of roboto
mono. Because gradle resolves that dependency.
This generates a "railroad diagram" svg image that can be embedded into
the docs for any function to explain it's syntax. It's basic, but it's
something we can iterate on.
It also generates a table of supported types from the list of types that
we test. It can be included in the docs for reference as well.
