Add bioinformatics category and related subcategories

[AliSajid]

Hi,

I have been working on quite a few bioinformatics related rust packages and thought it would be great to have a bioinformatics category and related subcategories. I've added those to the file here.

I'd be in favor of a biology category or subcategory.

Some related notes:

1. The science category does already broadly include biology-related crates.

   crates.io/src/boot/categories.toml

   Lines 495 to 500 in c03b893

   	[science]
   	name = "Science"
   	description = """
   	Crates related to solving problems involving physics, chemistry, \
   	biology, machine learning, geoscience, and other scientific fields.\
   	"""

2. lib.rs currently categorizes "biology, bioinformatics, genetics" under science::bio: https://lib.rs/science/bio. See also https://gitlab.com/lib.rs/main/-/blob/c4fc5e1e61b0c26f9034e7b36c254609eee6a94c/categories/src/categories.toml#L832-840. This is more generalized than what is proposed here, and I'm not sure how deep crates.io category levels are allowed to be.

It does make sense to a science:biology:* subcategories if that's what lib.rs already does. though I would argue Bioinformatics is distinct from Biology and could be nested directly under science:. Shall I make the change?

[jtgeibel]

@AliSajid yes, lets move these under science::*.

Also, a heads up that there is currently a proposed RFC (rust-lang/rfcs#3488) to deprecate categories and focus our efforts on improving keywords. However, the team has not made a decision on this RFC yet and we see no reason avoid using/adding categories until that decision is made.
