chore: increase precedence of |>, <|, $ parsers
...
@Kha Now, all parsers defined by `Init/Std/Lean` packages have
precedence >= `min` and <= `max`.
The only exception is `<|>` since it is an infix operator sharead with
the tactic DSL.
BTW, the meaning of `f $ a <|> b` changed with this commit.
It was `f (a <|> b)`, and now is `(f a) <|> b`. The problem is that
the precedence of the `$` parser is now greater than the `<|>` parser.
I will try another experiment where I make sure we do not "reuse"
term infix operators in the tactic DSL.

feat: heterogeneous OrElse and AndThen
...
@Kha I had a few issues similar to the `Append` issues.
We used a similar idiom for writing builtin parsers where we may write
```
def p : Parser := "foo " >> "bla "
```
as a shorthand for
```
def p : Parser := symbol "foo " >> symbol "bla "
```
I want to support `builtin syntax` one day :)
That being said, we should decide whether we keep `HAppend`, `HOrElse`,
and `HAndThen` or not.
The only one I wish I had in the past is `HAndThen`.
