improve typescript resolution

this PR changes the location of isTypescript detection to occur in one place that is more widely used so that it can be engaged more frequently to improve typescript resolution.

• improve resolution of typescript moduleIds

detect typescript parent to apply typescript condtions

When the resolver detects a typescript parent it can apply typescript conditions to resolve the moduleId. New conditions can be added for typescript situations as needed, this new behaviour is a starting point,

• pin node 20.4 at unit-test pipeline, last version of node before import.meta.resolve was reduced
• add workspaces unit-tests
• add detection of ".ts" parent extension for applying typescript conditions
• use moduleId and parent as internal names, following nodejs

v2.0.2 use node v20 ci, increment dependencies

return encoded url same as import.meta.resolve

return encoded url same as import.meta.resolve ,

• this, 'file:///path/to/indexfile/file%20name%20with%20spaces.js'
• rather than, 'file:///path/to/indexfile/file name with spaces.js'

add test and changes to support import.meta.url parent

Add test and changes to support import.meta.url parent. While exploring changes at esmock, it was discovered that esmock slightly modifies import.meta.url from the callee before passing along when calling resolvewithplus,

resolvewithplus('../../index.js', import.meta.url)

reduce install size 1kB

minified resolvewithplus.js is 50% smaller and total install size becomes 5.78kB, from 6.79kB

return fileurl-formatted paths, eg file:///path/to/module.js

Returning fileurl-formatted paths allows esmock to be simplified, where esmock previously needed to detect and convert resolvewithplus paths to fileurl-formatted paths. Returning fileurl-formatted paths also makes resolvewithplus more interchangeable with import.meta.resolve, which also returns fileurl-formatted paths,

• return fileurl paths, following the behaviour of import.meta.resolve
• added tests around export sugar esm patterns

parse esm patterns from nodejs' documentation

completed esm pattern parsing (big improvement)
