Download modal issues: API callout outdated, consistency of font sizes across tabs

[kandarpksk]

In the download modal, say when downloading a dataset, there are a couple of issues I noticed in the API tab:

1. The callout (text with blue background) to be updated to

• "Prefer to download via our API? Record the code snippet below and visit our API documentation to learn how. "
• Link to: https://chanzuckerberg.github.io/cryoet-data-portal/cryoet_data_portal_docsite_quick_start.html
• note: see Janeece's mockup in comments below

2. "Copy Python code snippet" changed to 14 px size using SDS variable "fontheaderS"

Recommend matching the callout copy from Download Singel tomogram via API:

• "Prefer to download via our API? Record the code snippet below and visit our API documentation to learn how. "

@junxini I finished adding info (above), should be ready to be assigned to eng.

everything non-style-related here has been addressed by @melissawm in #1256

however, the links differ. do we want to use the one in #1256 (https://chanzuckerberg.github.io/cryoet-data-portal/python-api.html) or in this issue @Janeece?

@kne42 thanks for catching this. Use the one in #1256 (https://chanzuckerberg.github.io/cryoet-data-portal/python-api.html) instead!
