Path collisions docs/src/{SUMMARY,summary}.md

[grekko]

Description

When cloning the current repository on a case-insensitive file system git warns about path collisions:

git clone https://github.com/thoughtbot/factory_bot.git tmp
…

warning: the following paths have collided (e.g. case-sensitive paths
on a case-insensitive filesystem) and only one from the same
colliding group is in the working tree:

  'docs/src/SUMMARY.md'
  'docs/src/summary.md'

Reproduction Steps

Create a case sensitive file system and clone the repository:

git clone https://github.com/thoughtbot/factory_bot.git tmp

Expected behavior

No issues for users with case-insensitive file systems.

Proposed changes

The 2 conflicting file paths are:

• docs/src/summary.md: An intro describing the contents
• docs/src/SUMMARY.md: An index file listing the relevant individual docs

How about renaming docs/src/summary.md to docs/src/readme.md and renaming docs/src/SUMMARY.md to docs/src/summary.md.

docs/src/readme.md should be read first when looking at the docs.
docs/src/summary.md seems to be the default pattern for similar files in sub-directories.

See PR proposal here #1581

I hope this does not break any links/references to the documents. I searched for references to SUMMARY.md in this repository but there could be external links or other dependencies on the file names 🤔

Maybe those who recently worked on the big docs refactoring have better knowledge and can check if my proposed changes are breaking anything.
